Ch 39: Atomic Structure Overview

About This Chapter

Look at this chapter as you study an overview of atomic structure. To do well on exams in physics and science, you need to feel confident with the subject matter, which is why these lessons are crafted to guide you through each topic and assist you with memorizing the key terms and definitions.

Atomic Structure Overview - Chapter Summary

Open up this chapter to gain access to an overview of atomic structure. Our instructors have taken this general topic and separated it into several smaller, more manageable lessons. These lessons can help you understand the formula for determining the amount of energy in a single photon of light. You can also review the lessons to become more skilled with quantum mechanics.

Recognize that you can move through this chapter in any way you want, either lesson by lesson, or by skipping around. After all, these lessons cover a wide range of topics, such as the properties of electrons, the movement of electrons inside atoms, ways to predict the properties of elements, subshells, orbitals, and shells. If you take the time to go through every lesson in this chapter, you will expand your knowledge base and be able to:

  • Describe the applications of Planck's constant
  • Identify the equation that represents Heisenberg's Uncertainty Principle
  • Analyze the implications of the quantum mechanical model
  • Explain atomic energy levels and electron configurations
  • Compare the rules and principles connected to atomic structures

To give you the best study materials available, we only employ the most knowledgeable instructors around. These are educators who have years of experience in science and physics, so they are highly familiar with these topics. In addition, most of our instructors have taught students at all levels, so they know how to use different approaches to reach a wider range of learners.

Planck's Constant: Formula & Application

1. Planck's Constant: Formula & Application

After watching this lesson, you will be able to explain what Planck's constant is and use the Planck-Einstein relation to calculate the energy in a photon of light. A short quiz will follow.

Heisenberg Uncertainty Principle: Definition & Equation

2. 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.

The Quantum Mechanical Model: Definition & Overview

3. 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.

Electron Configurations in Atomic Energy Levels

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.

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.
