The Bohr Model and Atomic Spectra

1. The Bohr Model and Atomic Spectra

Do you ever wonder where light comes from or how it is produced? In this lesson, we are going to use our knowledge of the electron configurations and quantum numbers to see what goes on during the creation of light.

Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

2. Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

Each electron inside of an atom has its own 'address' that consists of four quantum numbers that communicate a great deal of information about that electron. In this lesson, we will be defining each quantum number and explaining how to write a set of quantum numbers for a specific electron.

Electron Configurations in Atomic Energy Levels

3. Electron Configurations in Atomic Energy Levels

This lesson will explain what the electrons are doing inside the atom. Tune in to find out how we specify where they are located and how this location description will help us predict an element's properties.

Excited State in Chemistry: Definition & Overview

4. Excited State in Chemistry: Definition & Overview

This lesson defines excited states of electrons within atoms and their significance in chemistry. Learn about this state, see several examples, and complete the brief quiz.

Atomic Structures: Pauli Exclusion Principle, Aufbau Principle & Hund's Rule

5. Atomic Structures: Pauli Exclusion Principle, Aufbau Principle & Hund's Rule

This lesson discusses the three main rules that govern how electrons fit in the atomic structure by filling the shells, subshells, and orbitals. We will also review the basics of quantum numbers before learning these principles.

Diamagnetism & Paramagnetism: Definition & Explanation

6. Diamagnetism & Paramagnetism: Definition & Explanation

In this lesson, we learn more about electron configuration through the concepts of diamagnetism and paramagnetism. We will review electron structure in an atom, and define diamagnetism and paramagnetism.

Ground State Electron Configuration: Definition & Example

7. Ground State Electron Configuration: Definition & Example

The atom's electron structure is very important because it tells us about an atom's reactivity, and physical properties as well. In this lesson, we will cover the ground state electron configuration, which determines the electron's structure.

Electron Configurations in the s, p & d Orbitals

8. Electron Configurations in the s, p & d Orbitals

Getting confused by long lists that start with 1s and seem to go on forever? Don't worry, this lesson on electron configuration will help you understand how to describe electron placement in no time.

Heisenberg Uncertainty Principle: Definition & Equation

9. Heisenberg Uncertainty Principle: Definition & Equation

The Heisenberg uncertainty principle is one of the core concepts in quantum mechanics. In this lesson, we define the uncertainty principle and learn more about its implications for physical science.

Effective Nuclear Charge & Periodic Trends

10. Effective Nuclear Charge & Periodic Trends

This video lesson will describe effective nuclear charge and its role in explaining periodic trends. In particular, we will learn how to predict the trends in atomic radius and ionization energy using our knowledge of shielding and effective nuclear charge.

The Photoelectric Effect: Definition, History, Application & Equation

11. The Photoelectric Effect: Definition, History, Application & Equation

In this lesson, you will learn what the photoelectric effect is, how it was discovered, how it applies to everyday life, and the equation associated with it. A short quiz will follow.

Energy & Momentum of a Photon: Equation & Calculations

12. Energy & Momentum of a Photon: Equation & Calculations

After watching this lesson, you will be able to explain what wave-particle duality is, provide the equations for the energy and momentum of a photon of light, and use those equations to solve problems. A short quiz will follow.
