Ppt djy 2011 1 topic 7 atomic structure sl intro
This document discusses the development of atomic models from ancient Greek ideas to Rutherford's gold foil experiment and Bohr's model of the hydrogen atom. It introduces Dalton's atomic theory and developments like the plum pudding model, discovery of the electron, Rutherford's nuclear model, and Bohr's explanation of emission spectra. Key concepts covered include atomic structure, isotopes, atomic notation, and forces that hold the nucleus together.
Basic Atomic Structure
The document discusses the atomic model and structure of atoms. It states that atoms are comprised of protons, neutrons, and electrons, with protons and neutrons located in the central nucleus and electrons surrounding it in empty space. Protons are positively charged, electrons are negatively charged, and neutrons have no charge. The sizes of atoms and their components are described, with the nucleus being very small compared to the mostly empty space occupied by electrons. A brief history of atomic models is also provided.
Structure of atoms10
Scientists have been studying atoms since the 1800s using models to understand their structure and behavior. Early philosophers proposed the idea of atoms, while scientists like Dalton, Thomson, Rutherford, and Bohr developed atomic models through experiments. They discovered that atoms are mostly empty space with a small, dense nucleus at the center containing protons and neutrons, and electrons orbiting the nucleus. The number of protons determines the element, while isotopes of an element have different numbers of neutrons.
Power Notes Atomic Structure 2013
The document summarizes key developments in the atomic theory of matter:
1) Early Greek philosophers like Democritus proposed ideas of atoms as indivisible particles that make up all matter.
2) Scientists like Lavoisier, Dalton, and Thomson contributed experimental evidence and early atomic models, including Dalton's first modern atomic theory stating atoms are indestructible particles that combine in specific ratios.
3) Rutherford's gold foil experiment provided evidence that atoms are mostly empty space with a small, dense positively charged nucleus at the center, overturning the plum pudding model.

The rules of quantum mechanics such as Aufbau principle and Hund's rule are explained. Finally, it shows how the location of s, p, d and f orbitals relate to the periodic table and electron configurations.
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.

The document discusses the structure of the atom and the discovery of subatomic particles like electrons, protons, and neutrons. It describes experiments done by scientists like J.J. Thompson, Ernest Rutherford, and James Chadwick that led to the discovery of these fundamental particles. Key findings include the discovery of electrons as negatively charged particles in cathode rays, Rutherford's discovery of the nucleus through alpha particle scattering experiments, and Chadwick's discovery of the neutron through experiments with beryllium radiation.
The Structure of an Atom
Atoms are the basic building blocks of all matter and are made up of a nucleus containing protons and neutrons surrounded by electrons. John Dalton's atomic theory established that atoms are indivisible and that different elements are composed of different types of atoms. Rutherford discovered that the nucleus contains a concentrated positive charge and most of an atom's volume is empty space. Niels Bohr's model represented electrons orbiting the nucleus in fixed energy levels like planets around the sun, explaining atoms' distinct properties and how they form bonds.
Atomic structure
1. Atoms are the building blocks of matter and too small to see easily. They have a nucleus containing protons and neutrons surrounded by electrons.
2. The nucleus contains protons, which have a positive charge, and neutrons, which have no charge. Electrons orbit the nucleus and have a negative charge.
3. Rutherford's gold foil experiment showed that atoms have small, dense nuclei, overturning the plum pudding model. This led to the development of the Rutherford-Bohr model in which electrons orbit the nucleus in defined energy levels.
How to draw bohr diagrams (slideshare)
1) Atoms have a nucleus surrounded by electron shells. The number of electrons equals the atomic number.
2) Electron shells can hold a certain number of electrons and fill from the innermost shell outward. The outermost shell electrons are called valence electrons.
3) To draw a Bohr diagram, find the element and atomic number, determine the number of electron shells based on its period, draw the nucleus and shells, and add the correct number of electrons in allowed shells moving counter-clockwise.
Presentation for Radioactivity
Atoms are made up of protons, neutrons, and electrons, with the number of protons defining the element. Different isotopes of an element have the same number of protons but different numbers of neutrons. Radioactive decay occurs spontaneously as nuclei emit alpha, beta, or gamma radiation to become more stable, conserving nuclear particles but decreasing mass.

Structure of an Atom
- Dalton's model proposed that all matter is made of tiny particles called atoms, all atoms of the same element are alike but different from other elements, and compounds form from atoms combining in fixed proportions. Thomson's model pictured the atom as a positively charged sphere with electrons embedded within it. Rutherford's model showed that the atom's positive charge and most of its mass are concentrated in a tiny, dense nucleus at the center with electrons orbiting outside. The parts of an atom include the nucleus containing protons and neutrons at its center, surrounded by electrons. Protons have a positive charge while neutrons have no charge. Electrons have a negative charge and much less mass than protons or neutrons.

The document discusses the history of atomic theory from ancient Greek philosophers to modern atomic structure. It begins with Democritus proposing atoms in 460 BC, though Aristotle disagreed. In the early 1800s, John Dalton revived atomic theory and proposed atoms combine in whole number ratios, explaining conservation of mass. In the early 1900s, J.J. Thomson, Ernest Rutherford, and Niels Bohr contributed atomic models. Atoms are made of electrons, protons, and neutrons. Isotopes have the same number of protons but different neutrons. Unstable nuclei undergo radioactive decay through alpha, beta, or gamma radiation.
