Ch 2: Basics of the Atom
About This Chapter
Basics of the Atom - Chapter Summary and Learning Objectives
Take advantage of our instructors' expertise to develop your understanding of the fundamental units of matter. Illustrated videos can help you visualize the placement of an atom's subatomic particles and wrap your head around what's involved in calculating an element's atomic mass. Topics of instruction include:
- Properties of subatomic particles
- Valence levels in the electron shell
- Isotopes of an element
| Video | Objective |
|---|---|
| The Atom | Explore the characteristics of protons, neutrons and electrons. Study these subatomic particles' organization in and around the atomic nucleus. |
| The Electron Shell | Examine the relationship between an atom's energy level and the number of electrons in its electron shell. Learn how valence levels are used to group elements in the periodic table. |
| Isotopes and Average Atomic Mass | Discover the connection between an element's isotopes and its average atomic mass. |
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?
2. 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?
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.
