Ch 7: Atomic Structure & Nuclear Chemistry

About This Chapter

The lessons in this chapter flesh out a variety of topics related to atomic structure and nuclear chemistry, including information about protons, neutrons, molar volume, electrons, and atomic mass. Students will be prepared to apply relevant knowledge through video lessons taught by professional instructors.

Atomic Structure and Nuclear Chemistry - Chapter Summary

This chapter provides a detailed yet time-efficient look into several terms and concepts key to the study of atomic structure and nuclear chemistry, with a focus on the Bohr Model, the electron shell, and specific aspects of atomic mass and isotopes. Additionally, the lessons cover the following:

  • The atomic spectra and nucleus
  • Protons and neutrons
  • Atomic and mass number
  • Electron activity inside an atom
  • Avogadro's number
  • Molar volume and mass

With both a video and transcript of each lesson, students will be able to choose the form of learning that suits them best. Both methods include features that make navigation simple, with key terms in bold throughout the transcripts making it easy to spot main points, and the timeline feature underneath the videos allowing watchers to skip around the lesson's core topics.

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.

Atomic Nucleus: Definition, Structure & Size

2. Atomic Nucleus: Definition, Structure & Size

The atomic nucleus is the central part of the atom. There is a lot to be told by the structure of the atomic nucleus. This lesson goes through the structure of the atomic nucleus and other factors that the atomic nucleus tells us.

The Electron Shell

3. The Electron Shell

You may be familiar with the role of electrons in electrical devices, but did you know that electrons also determine the chemical reactivity of everything around you?

Protons: Definition, Charge & Mass

4. Protons: Definition, Charge & Mass

Protons can be found in the nucleus of every atom. While originally it had been thought that protons were a fundamental particle, recent research has shown that protons are made of quarks. This lesson will cover the properties of the proton.

Neutrons: Definition & Concept

5. Neutrons: Definition & Concept

Neutrons are the big guys of the atom. This lesson explains the structure of the neutron, its properties, and some of its influences on the function of the atom.

Atomic Number and Mass Number

6. Atomic Number and Mass Number

Atoms are the basic building blocks of everything around you. In order to really understand how atoms combine to form molecules, it's necessary to be familiar with their structure. In this lesson, we'll dissect atoms so we can see just what really goes into those little building blocks of matter.

What is Atomic Mass? - Definition & Examples

7. What is Atomic Mass? - Definition & Examples

Atomic mass is a characteristic of an atom that is a measure of its size. It is plays a major role in the chemical properties of elements. This article discusses atomic mass and how it is calculated.

What Are Isotopes? - Definition, Types & Examples

8. What Are Isotopes? - Definition, Types & Examples

Not all atoms of an element are identical - atoms of the same element can have different numbers of neutrons. These different versions of the same element are called isotopes. In this lesson, we will discuss the examples and types of isotopes.

Isotopes and Average Atomic Mass

9. Isotopes and Average Atomic Mass

When you drink a glass of water, you are actually drinking a combination of heavy water and light water. What's the difference? Is it harmful? This video will explain the difference between the two types of water and go into detail on the significance of the different isotopes of elements.

Electron Configurations in Atomic Energy Levels

10. 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.

Avogadro's Number: Using the Mole to Count Atoms

11. Avogadro's Number: Using the Mole to Count Atoms

How do we move from the atomic world to the regular world? Because atoms are so tiny, how can we count and measure them? And what do chemists celebrate at 6:02 AM on October 23rd each year? In this lesson, you will be learning how Avogadro's number and the mole can answer these questions.

Molar Volume: Using Avogadro's Law to Calculate the Quantity or Volume of a Gas

12. Molar Volume: Using Avogadro's Law to Calculate the Quantity or Volume of a Gas

Have you ever wondered why a balloon expands when you blow it up? How something as light as air is able to exert a force large enough to inflate a balloon? In this lesson, you will learn about the relationship between the volume of a container filled with a gas and the number of gas particles that container holds. This relationship is known as Avogadro's Law.

What is Molar Mass? - Definition, Formula & Examples

13. What is Molar Mass? - Definition, Formula & Examples

Compounds have mass, and this is what we call the molar mass. In this lesson, we will discuss the molar mass and go over examples on how to calculate it.
