Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

1. Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

Imagine firing a bullet at a piece of tissue paper and having it bounce back at you! You would probably be just as surprised as Rutherford when he discovered the nucleus. In this lesson, we are going to travel back in time and discuss some of the major discoveries in the history of the atom.

Protons: Definition, Charge & Mass

2. 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

3. 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

4. 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

5. 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.

Avogadro's Number: Using the Mole to Count Atoms

6. 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.

The Bohr Model and Atomic Spectra

7. 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.
