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.

Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

3. 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.

Isotopes and Average Atomic Mass

4. 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

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.

Atomic Structures: Pauli Exclusion Principle, Aufbau Principle & Hund's Rule

6. 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.

The Law of Conservation of Mass: Definition, Equation & Examples

7. The Law of Conservation of Mass: Definition, Equation & Examples

Read about the law of conservation of mass, its role in chemistry, and its importance in the universe. Learn the equation, review examples, and test your knowledge of the material with a short quiz.

Diamagnetism & Paramagnetism: Definition & Explanation

8. Diamagnetism & Paramagnetism: Definition & Explanation

In this lesson, we learn more about electron configuration through the concepts of diamagnetism and paramagnetism. We will review electron structure in an atom, and define diamagnetism and paramagnetism.

Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

9. Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

Each electron inside of an atom has its own 'address' that consists of four quantum numbers that communicate a great deal of information about that electron. In this lesson, we will be defining each quantum number and explaining how to write a set of quantum numbers for a specific electron.

The de Broglie Hypothesis: Definition & Significance

10. The de Broglie Hypothesis: Definition & Significance

The de Broglie hypothesis states that particles of matter can behave as both waves and particles, just like light. In this lesson, we'll learn the basics of the de Broglie hypothesis and how it related to other theories released at the same time.

Ionic Bonds: Definitions and Examples

11. Ionic Bonds: Definitions and Examples

Did you know that when atoms stick together to form molecules, they gain and lose electrons, making them negatively or positively charged? In this lesson, you will learn how cations and anions form one type of chemical bond called an ionic bond.

How Compounds and Molecules Are Built From Elements

12. How Compounds and Molecules Are Built From Elements

Did you know that elements are like people and have different personalities? A few elements are very shy and love to be left alone. Others are very social and prefer to hang out with friends. In this lesson we will discuss how elements build molecules and compounds.

Polar and Nonpolar Covalent Bonds: Definitions and Examples

13. Polar and Nonpolar Covalent Bonds: Definitions and Examples

Did you know that some types of chemical bonds behave similarly to the way that children play with toys? In this lesson, you will learn about two types of bonds called polar and nonpolar covalent bonds.

Using Atoms and Ions to Determine Molecular Formulas

14. Using Atoms and Ions to Determine Molecular Formulas

In this lesson, you will learn how atoms and ions determine molecular formulas. You will understand how molecular formulas tell information about the type and quantity of atoms involved in a molecule. Lastly, we will discuss how to write a molecular formula for an ionic compound.

What Are Elements?

15. What Are Elements?

Look around you. What do you see? Elements are everywhere. They are the building blocks of all matter on Earth. In this lesson, we will discuss what an element is, how elements are written as symbols, and how elements are the building blocks of all matter.
