Ch 1: AQA A-Level Chemistry: Atomic Structure

About This Chapter

Use the lessons in this chapter to review what you've learned about the structure of atoms. This chapter will help as you study for the AQA A-Level Chemistry exam.

AQA A-Level Chemistry: Atomic Structure - Chapter Summary

Atoms are the building blocks of all matter. With the lessons in this chapter, you will get to take a peek into the atom, so you can explore exactly how they are structured. Once you've garnered sufficient knowledge, you can accurately answer AQA A-Level Chemistry exam questions. Specifically, you'll examine the following through this chapter's lessons:

  • The atom
  • Mass number and average atomic mass
  • Atomic number
  • Isotopes
  • Electron shell
  • Configurations of electrons

We strive to make learning an inviting and pleasurable experience. Our instructors have created videos to help keep you engaged in the learning process. The videos' transcripts are included as a great resource from which to jot down information. You can take self-assessment quizzes as you work your way through the chapter. A chapter exam can be taken after you complete the lessons to apply all that you have learned.

The Atom

1. The Atom

Tune into this lesson to find out what matters about matter. What exactly is an atom? And, how do the atoms that make up the elements in the periodic table differ from one another?

Atomic Number and Mass Number

2. 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.

Isotopes and Average Atomic Mass

3. 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.

The Electron Shell

4. 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?

Electron Configurations in Atomic Energy Levels

5. 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.
