History of Atomic Structure
Democritus first proposed the idea of atoms in 400 BC, stating that all matter is composed of tiny indivisible particles called atoms that differ in size and shape. John Dalton later elaborated on this theory in the 1800s, postulating that atoms of different elements have unique properties and can combine to form compounds. J.J. Thomson's discovery of the electron in the late 1800s led to the plum pudding model of the atom. However, Ernest Rutherford's gold foil experiment in the early 1900s revealed that atoms are mostly empty space with a tiny, dense nucleus at the center, containing positive charge. Niels Bohr then incorporated Rutherford's findings into his 1913 model of the atom, proposing that electrons

Module 2 atom inside out (grade 8)
J.J. Thomson discovered the electron in 1897 through his cathode ray experiment and proposed the "plum pudding" model of the atom in 1904. Later experiments provided evidence that atoms are made of even smaller subatomic particles. In the 1910s, Rutherford discovered the nucleus through his gold foil experiment and proposed a nuclear model of the atom. In 1932, Chadwick discovered the neutron through experiments bombarding beryllium with alpha particles. Atoms are now understood to have a small, dense nucleus containing protons and neutrons, surrounded by electrons in orbit.
Structure of atom ppt
Atoms are the basic building blocks of all matter. John Dalton proposed that atoms are indivisible and identical for each element. Rutherford discovered that atoms have a small, dense nucleus at the center surrounded by electrons. Niels Bohr modeled atoms with electrons orbiting the nucleus in fixed energy levels or shells. The nucleus contains protons and neutrons, while electrons orbit outside. The number of protons determines the element, and protons and neutrons together equal the mass number.
Atomic Structure
This document discusses early atomic theories and models of matter. It describes the theories of Aristotle, who believed that matter was continuous with no empty spaces, and Democritus, who proposed that matter was discontinuous and could be divided into smaller particles called atoms. The document then focuses on John Dalton's atomic model from the early 1800s, which proposed that all matter is composed of atoms, atoms of the same element are identical, atoms of different elements differ, and atoms combine in chemical reactions. Dalton's model helped establish the foundations of modern atomic theory.
Atomic Structure
The document discusses the structure of atoms. It defines an atom as the smallest particle of an element that retains its identity in chemical reactions. It describes how atoms are composed of subatomic particles including protons, neutrons, and electrons. It discusses how the number of protons determines the element, the number of electrons usually equals the number of protons, and the mass number is the total of protons and neutrons. Isotopes are defined as atoms of the same element with different numbers of neutrons. The document also discusses electron shells and valence electrons.
Bohr Rutherford Atomic Model
The document describes the Bohr-Rutherford atomic model. It states that the atom consists of a small, dense nucleus containing protons and neutrons, surrounded by electrons in shells. The atomic number equals the number of protons, and a neutral atom has the same number of protons and electrons. Electrons are located in shells outside the nucleus, with the first shell holding 2 electrons and subsequent shells able to hold more. Diagrams illustrate atoms showing their arrangement of subatomic particles. Examples are provided of looking up atomic properties and drawing Bohr-Rutherford diagrams for different elements.
Atomic theory
This document outlines the development of atomic theory from ancient Greek philosophers to modern physics. It describes key contributors such as Democritus, Dalton, Thomson, Rutherford, Bohr, and Schrodinger who proposed models of the atom based on experiments. The modern atomic theory is that atoms contain a nucleus of protons and neutrons surrounded by electrons in electron clouds, and that elements are defined by their atomic number while isotopes differ in neutron number. The four fundamental forces that act on atoms are also summarized.
Atomic number and mass number
This document provides information about atomic structure, including the three main subatomic particles - protons, neutrons, and electrons. It discusses the key properties of each particle, including their location within the atom, mass, and electrical charge. Protons determine the element and have a positive charge. Neutrons are neutral and have a similar mass to protons. The number of protons and neutrons gives an atom its identity and mass number.
Thompson & Rutherford
This document discusses J.J. Thomson and Ernest Rutherford's atomic models. It summarizes Thomson's cathode ray experiments that discovered the electron. Thomson believed atoms were a uniform positive sphere with electrons embedded in it. The document also describes Rutherford's model with a small, dense positive nucleus surrounded by electrons in orbit. It lists the key properties of cathode rays that revealed electrons are negatively charged and have mass.
Structure of Atom
This lesson plan outlines a science class on the atomic structure. It includes general and specific objectives of the lesson, a knowledge pre-test, and an outline of the presentation. The presentation will discuss early atomic models proposed by Thomson and Rutherford, and the drawbacks of Rutherford's model. It will then explain Niels Bohr's model of the atom, including his postulates that electrons orbit in discrete energy levels and absorb or emit energy in quantized amounts when changing orbits. Students will learn about the distribution of electrons in shells and orbits in atoms.
Chapter 4 - The Atom
This document summarizes the history and development of the atomic theory and periodic table. It discusses early Greek philosophers' ideas about atoms, John Dalton's atomic theory in the early 1800s, J.J. Thomson's discovery of electrons in the late 1800s, Ernest Rutherford's discovery of the nucleus in 1909, and the discovery of neutrons in 1930 which completed the modern atomic model. It also explains how atoms are composed of protons, neutrons and electrons, how atomic and mass numbers are used to identify elements and isotopes, and how average atomic masses are calculated based on the relative abundances of isotopes in nature.
Chapter 4 atomic structure
This document summarizes key concepts from Chapter 4 on atomic structure:
1) It describes early atomic theories from Democritus and Dalton, including Dalton's postulates that atoms are indivisible and atoms of different elements have different properties.
2) Modern research has shown atoms are composed of subatomic particles like electrons, protons, and neutrons. Experiments by Thomson, Millikan, Rutherford and others led to discoveries about these particles and the nuclear model of the atom.
3) Isotopes are atoms of the same element that differ in number of neutrons. Atomic mass is an average that takes isotopic abundance into account. The periodic table organizes elements based on repeating atomic properties.
CST Review_Atoms and Atomic Structure
All isotopes of an element have the same number of protons. Isotopes are forms of an element that have different numbers of neutrons. Isotopes are named by writing the element name followed by the mass number, which is the number of protons plus neutrons. The average atomic mass shown for an element on the periodic table takes into account the relative abundance of all its isotopes.
Physical science 4.1 : Development of Atomic Theory
Democritus was one of the first to propose the idea of atoms in 440 BCE, suggesting that matter is made up of tiny indivisible particles called atoms. In the early 1900s, experiments led scientists to develop more accurate models of the atom. Rutherford discovered the nucleus in 1909 by firing positively charged particles at a gold foil and observing some particles deflecting, indicating a small, dense nucleus. Bohr then proposed in 1913 that electrons orbit the nucleus in distinct energy levels. The modern atomic theory describes the regions where electrons are likely to be found as electron clouds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Powr notes atomic structure day 3
- 1. Today in Science You will Need: 1)Pencil, Colored Pencils, Highlighters or Markers 2)Power Notes – Atomic Structure– 2 pages 4 sides -Picked up Friday and Monday 3)Last day to turn in work for this Quarter is tomorrow, Oct. 23rd
- 2. Reminders 1)Test Corrections and Signature- Please do corrections directly on test- Due Tomorrow 1)Tell WHY you missed the multiple choice questions 2)Retakes for Test #2: 101/145 or below 1)Thur 24th – Before School and Lunch 2)Fri. 25th – Lunch 3)Mon. 28th – Before School and Lunch 4)Tues 29th – Before School and Lunch 5)Thur. 31st – Before School and Lunch 3)Last Day to Turn in work for this quarter is Tomorrow: Wednesday, Oct. 23rd 4) Still grading Density Assignment.
- 3. Topic: Power Notes- Atomic Structure Do we understand everything????
- 4. Democritus 400 BC Greece - stated that all matter is made up of atoms. He also stated that atoms are eternal and invisible and so small that they can’t be divided, and they entirely fill up the space they’re in Lavoisier 1789 France - provided the formula for the conservation of matter in chemical reactions, and also distinguished between an element and a compound • 1st idea of “atoms” • Believed all matter is made up of tiny particles separated by space • Named particles “atomos” which means indivisible. • Founder of modern chemistry • 1st carefully controlled experiments providing evidence to the Law of Conservation of Mass
- 5. Dalton 1766-1844 England - formed the 1st atomic theory, which states that all matter is composed of tiny, indestructible particles called atoms that are all alike and have the same atomic weight. 1st MODERN Atomic Theory 1.All matter made up of tiny indivisible particles called atoms 2.Atoms of the same element have identical properties 3.Atoms of different elements have different properties 4.Atoms combine in a specific ratio to form compounds 5.A specific compound is always made up of atoms in a specific proportion.
- 6. Thomson 1897 Plum Pudding Model 1.Negative particles scrambled into the “dough” of the positive particles. England - discovered the electron and developed the plumpudding model of the atom. Rutherford 1898 England - used the results of his gold-foil experiment to state that all the mass of an atom was in a small positively-charged ball at the center of the atom. Gold Foil Experiment 1.Atoms are mostly empty space 2.All the Mass of an atom is in the positively charged ball in the center of the structure.
- 7. •Scientists look for patterns in data and passed experiments to What is the difference between the EXPECTED PREDICT what they think might happen. RESULTS &OBSERVED •When scientists actually do an RESULTS? experiment their observed results may be different than what they EXPECT to happen because of passed information. •However, many times the expected results are in fact, what is observed.
- 8. Bohr 1922 Denmark - stated that the electrons moved around the nucleus in successively large orbits. He also presented the Bohr atomic model which stated that atoms absorb or emit radiation only when the electrons abruptly jump between allowed, or stationary, states. Schrödinger (Schroedinger ) Austria - introduced the 1930 Shroedinger Equation, a wave equation that describes the form of the probability waves that govern the motion of small particles and how these waves are altered by external influences. “Planetary” atom model 1.Believed the atom structure was like our solar system: nucleus in the middle like the sun and the electrons orbiting like the planets. Wave Mechanic Model 1.Planetary model was too specific 2.Rather: electrons vibrate around the outside of the nucleus- can only predict where they are most like to be 3.QUARKS – protons, neutrons and electrons made up of some of these smaller particles. 4.http://library.thinkquest.org/05aug/01087/quarks.html
- 9. Basic Atomic Structure Today scientists agree on the three basic subatomic particles that make up all atoms. Bohr Model for Lithium Electron = 3 (not to scale) P= 3 + N = 3 0 Where is most of the mass in the Atom? Where is most of the volume in the Atom? NUCLEUS Outside the Nucleus; Electron Cloud
- 10. Nucleus • • • • Electron • • • Contains protons(+) and Neutrons (0) Holds most of the mass of the atom Very small compared to the entire size of the atom Most dense part of the atom Negatively charged subatomic particle Found outside the nucleus in the electron cloud Smallest particle; mass = 1/1836th of the atom
- 11. Proton • • • • • Neutron • • • • • • Positively charged subatomic particle Found in the nucleus Mass = 1 amu (atomic mass unit) # of protons in an atom IDENTIFIES the atom (which element) # of protons in the nucleus of an atom called the atomic number Zero charge Mass = 1 amu Do NOT affect the identity of the atom Found in the nucleus Same atom of an element can have varying amounts of neutrons (isotope) Adding the total number of protons & neutrons = Atomic Mass Number http://www.sawyerscience.com/Units/unit2/atoms_compounds.html
- 12. All atoms found on the • Periodic Table are • Isotope Neutral – same # of protons(+) and # of electrons(-) Atoms of the same element with same number of protons and different number of neutrons. nucleus Hydrogen has 3 natural occurring ISOTOPES: Protium, Deuterium and Tritium nucleus Proton Protiu m are All ROGEN have l HYD use al a bec oton. r 1p nucleus Tritium Deuteriu m Neutro n
- 13. Atomic MASS IONS REVIEW & REFLECT • On the Periodic Table represents a weighted average of the mass of all naturally occurring isotopes of each element. (based on mass and abundance of each isotope). • When atoms gain or lose electrons they become charged. (number of protons (+) and electrons (-) particles are NOT EQUAL) + -
- 14. Homework 1)Test Corrections & Signature- Due Tomorrow-Wed, Oct. 23rd 2)1 days left to turn in late or missing work after today. 3)Extra Credit Crossword Puzzle – Due Tomorrow Do You see HOW the periodic table and the Atomic Structure are RELATED?
