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.
2. The Quantum Mechanical Model: Definition & Overview
Discover the quantum mechanical model of the atom and determine the way in which it is different from the orbital model. Learn about the quantum mechanical properties of electrons, then take a quiz to test what you know.
3. Using Orbital Hybridization and Valence Bond Theory to Predict Molecular Shape
You'll learn how to explain how shapes of molecules can be predicted using valence bond theory and hybridization. When finished, you'll understand the difference between sigma and pi bonds and how the VSEPR theory, along with the hybridization theory, helps predict the shape of a molecule.
4. 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.
5. The 7 Major Regions of the Electromagnetic Spectrum
This lesson will walk you through each of the major regions of the electromagnetic spectrum. Explore the unique characteristics of X-rays, microwaves, radio waves, UV rays, infrared, gamma rays, and of course, visible light.
6. Calculating Formal Charge: Definition & Formula
It is important to know what the valence electron contribution is from each atom in a molecule. In order to determine this, we calculate the formal charge of the atoms. In this lesson, we will discuss how to determine formal charge.
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.
