Electron configuration
This document provides information about electron configuration, which describes the arrangement of electrons in an atom. It discusses three main principles for determining electron configuration:
1. The Aufbau principle states that electrons occupy the lowest available energy orbitals. Energy levels are filled in order of increasing energy, with s orbitals having the lowest energy followed by p, d, and f orbitals.
2. Hund's rule states that electrons occupy different orbitals within the same energy level with parallel spin before pairing electrons with opposite spin in the same orbital.
3. The Pauli exclusion principle allows no more than two electrons to occupy the same orbital, and these electrons must have opposite spins.

This document discusses the arrangement of electrons in atoms. It explains how to use the aufbau principle, Pauli exclusion principle, and Hund's rule to determine electron configurations and draw spin diagrams. It notes there can be exceptions to the normal rules for electron configurations. It also describes how to draw modified Bohr diagrams showing the arrangement of electrons in an atom.
Electron configuration
Electron configuration represents the arrangement of electrons in an atom's orbital shells and subshells. There are three main rules that determine electron configuration: the Aufbau principle, which states that orbitals are filled in order of increasing energy; the Pauli exclusion principle, where no two electrons can have the same quantum numbers; and Hund's rule, where orbitals in a subshell are singly occupied with parallel spins before pairing. Electron configuration can be written out or represented through orbital diagrams, the periodic table, or Möller diagrams.
electronic configuration
The document discusses electronic configurations of atoms. It explains that the electron configuration represents the arrangement of electrons in an atom's orbital shells and subshells in its ground state, and can also represent ionized atoms. Many physical and chemical properties correlate to unique electron configurations, especially the valence electrons in the outermost shell. Electrons fill orbitals according to increasing energy levels and subshells in a set order. Orbital diagrams, spdf notation, and noble gas notation are used to represent electron configurations.
What is electronic configuration
This document defines and explains electronic configuration, which shows the distribution of electrons in an atom or molecule. It describes electron shells as the areas where electrons orbit, and atomic orbitals as specific regions that electrons can occupy according to set filling orders. Overlap orbitals occur when electrons share the same orbital space, as in the H2 molecule. The document also provides an example of how to write electronic configurations and use an electron configuration table to visualize the notation.

It explains that electrons are arranged in shells and subshells around the nucleus, with the subshells labeled s, p, d, and f. The order that electron subshells are filled is provided, with exceptions to a simple ordering. Examples of writing the electronic configuration of different elements are given by asking a series of questions.
Electron configuration
This document discusses electron configuration and how electrons are arranged in atoms. It introduces the Bohr model of electron shells and energy levels, then describes more accurate quantum mechanical models of electron orbitals. The document explains the Aufbau principle of filling orbitals from lowest to highest energy, the Pauli exclusion principle of maximum two electrons per orbital, and Hund's rule of filling orbitals within the same level. It outlines the shapes and notations of s, p, d, and f orbitals and how they relate to the periodic table and electron configuration notation.
Unit 4 1 orbitals introduction
Electrons in atoms occupy specific energy states called orbitals. Orbitals represent the region where an electron is most likely to be found within its energy state. For example, the orbital occupied by the single electron in a hydrogen atom is shown as a cloud indicating a higher probability of finding the electron in the darker regions. While common diagrams depict electrons orbiting the nucleus like planets, this is not an accurate model - electrons occupy probabilistic regions described by orbitals rather than following precise orbits.

This document discusses electron configuration and the principles that govern how electrons are arranged in atoms. It explains that electrons exhibit wave-like properties and occupy regions of space called atomic orbitals. The distribution of electrons in atoms, known as electron configuration, follows three main principles: the Pauli Exclusion Principle limits orbitals to two electrons of opposite spin; the Aufbau Principle states that orbitals are filled from lowest to highest energy; and Hund's Rule specifies that orbitals are singly occupied with parallel electron spins before double occupation occurs.
Electrons
This document discusses the development of atomic structure models from Rutherford to the modern quantum mechanical model. It introduces Bohr's model which proposed that electrons exist in discrete energy levels. The quantum mechanical model uses mathematics to determine electron energies and probabilities.

Rules like the Aufbau principle, Pauli exclusion principle, and Hund's rule govern how electrons fill atomic orbitals in an atom's electron configuration.
Atom notes
- Atoms are made up of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit in energy levels around the nucleus.
- The number of protons determines the element and is equal to its atomic number. The total number of protons and neutrons determines the atomic mass of an element.
- Electrons occupy different energy levels based on their distance from the nucleus, with the first level holding up to 2 electrons and subsequent levels holding more. Valence electrons in the outermost level determine an element's reactivity.

Chemical Bonding Part 1
A chemical bond is a force that holds atoms together, causing them to function as a single unit. There are three main types of bonds: ionic bonds, polar covalent bonds, and covalent bonds. Ionic bonds form between a metal and nonmetal when electrons are transferred from one atom to the other, creating oppositely charged ions. Polar covalent bonds involve the unequal sharing of electrons between two nonmetals. Covalent bonds equally share electrons between two nonmetals. Bonds are important because they determine how atoms interact and undergo chemical reactions.

The Aufbau principle states that electrons fill the lowest available energy levels first from the s, p, d, and f orbitals. Hund's rule and the Pauli exclusion principle dictate how electrons pair up within orbitals. Noble gas notation provides a shorthand for writing electron configurations. Valence electrons are those in the outermost shell and determine an element's chemical properties.

Electron configurations describe the arrangement of electrons in an atom. Electrons occupy different energy levels and orbitals within these levels. The Aufbau principle states that electrons fill the lowest available energy levels first from the s, p, d, and f orbitals. Hund's rule specifies that electrons occupy different orbitals within the same energy level before pairing up. The Pauli exclusion principle indicates that no two electrons can occupy the same orbital. Noble gas notation provides a shorthand for writing electron configurations.
single drop chemistry
This document provides an overview of electron structure and atomic organization. It discusses electromagnetic radiation and how different wavelengths relate to energy. Bohr's theory of the atom is introduced, explaining that electrons reside in quantized energy levels. The document outlines the organizational structure of electrons in atoms, including shells, subshells, and orbitals. It describes the shapes and properties of s, p, d, and f orbitals. Atomic electron configurations are related to an element's physical and chemical properties according to its valence shell.
Quantum Mechanic Model
The four quantum numbers specify the location of electrons in an atom. The principal quantum number (n) determines the electron's energy level and orbital size. Higher n means a larger orbital farther from the nucleus, increasing the atom's energy. The angular momentum quantum number (l) corresponds to an orbital's subshell type (s, p, d, f). The third and fourth quantum numbers further specify an electron's orientation. Electrons fill atomic orbitals according to Aufbau principle, Pauli exclusion principle, and Hund's rule to achieve the lowest energy configuration.

Activity 3. VII.Enrichment activity.pptx
Atomic orbitals are mathematical functions that describe the probability of finding an electron around an atom's nucleus. They are dependent on the values of four quantum numbers: principal, azimuthal, magnetic, and spin. Each atomic orbital can hold a maximum of two electrons with opposite spin. The number and type of atomic orbitals in each energy level depends on the principal quantum number n. Lower energy levels like s and p orbitals fill first before higher energy d and f orbitals. Electrons arrange themselves in atomic orbitals from lowest to highest energy to achieve the most stable configuration.
Orbitals hl
The document discusses orbitals and quantum numbers. It introduces the four quantum numbers - principal (n), azimuthal (l), magnetic (ml), and spin (ms) - that describe an electron's location and properties. The classical view of electrons orbiting the nucleus like planets gave way to the modern atomic model where electrons exist as probabilistic wave functions within orbitals. Orbitals are regions of high probability of finding an electron and come in s, p, d, and f shapes depending on the quantum numbers. Electron configurations use these orbitals to describe the arrangement of electrons in atoms and predict properties.
Qrt-2-Week-1-Module-1-Lesson-1.pptx
This document provides an overview of the quantum mechanical model of the atom. It discusses key concepts like the development of atomic models, electron configuration, quantum numbers, electron orbitals, and energy levels. Some key points:
- The quantum mechanical model describes the probable locations of electrons in an atom and how they can have discrete energy levels. It improved upon earlier planetary and Bohr models.
- Electrons occupy specific orbitals and energy levels denoted by quantum numbers like principal and azimuthal quantum numbers.
- Electron configuration notation specifies the distribution of electrons across orbitals based on Aufbau's principle and other rules.
- Transitions between energy levels explain the emission or absorption of photons and thus the colors
Electrons in Atoms
The document discusses the development of atomic models from Dalton to Bohr and beyond. It describes Rutherford's discovery of the nucleus and Bohr's model of electrons in fixed orbits around the nucleus. Later, the quantum mechanical model was developed, restricting electrons to specific energy levels rather than exact orbits. This modern model determines the probability of finding electrons in different locations around the nucleus.
Electrons in atoms
The document discusses the historical development of atomic models from Dalton to Bohr and beyond. It introduces John Dalton's early model of atoms as indivisible particles with no internal structure in 1863. Later models incorporated the discoveries of the electron by J.J. Thomson in 1897 and the nuclear structure of atoms by Ernest Rutherford in 1911. Niels Bohr's 1913 model proposed that electrons orbit the nucleus in fixed, quantized energy levels. This laid the foundations for understanding atomic emission spectra and the quantum mechanical model that later replaced Bohr's model.
Electron configuration cheat sheet
This document provides a summary of key concepts for electron configuration in high school chemistry, including:
