The Photoelectric Effect: Definition, History, Application & Equation

1. The Photoelectric Effect: Definition, History, Application & Equation

In this lesson, you will learn what the photoelectric effect is, how it was discovered, how it applies to everyday life, and the equation associated with it. A short quiz will follow.

Wave-Particle Duality & the Davisson-Germer Experiment

2. Wave-Particle Duality & the Davisson-Germer Experiment

After watching this video, you should be able to explain what wave-particle duality is, explain how the Davisson-Germer experiment contributed to our evidence for it, and use the de Broglie equation to solve problems. A short quiz will follow.

Atomic Nucleus: Definition, Structure & Size

3. 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.

What Are Isotopes? - Definition, Types & Examples

4. 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.

What is an Isobar? - Definition & Examples

5. What is an Isobar? - Definition & Examples

Learn the definition of an isobar, then explore the way in which they are applied on a map and what they show. After completing the lesson, you'll understand why isobars are useful tools for predicting weather.

The Bohr Model and Atomic Spectra

6. 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.

Isotopes and Average Atomic Mass

7. 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.

Radioactive Decay: Definition, Formula & Types

8. Radioactive Decay: Definition, Formula & Types

In this lesson, we'll discuss radioactive decay and learn the terms parent nucleus, daughter nucleus, and half-life. We'll also examine three types of radioactive decay.

Mass and Energy: Description and Interchangeable Relationship

9. Mass and Energy: Description and Interchangeable Relationship

Einstein used E = mc^2 to prove that mass and energy are relative to each other. This lesson describes how energy can be converted into mass and mass into energy. Experimental results from particle accelerators are used to demonstrate the relative nature of mass and energy.

Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

10. Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

What can the sun do that we can't? How do carbon atoms 'date'? Are radioactive isotopes helpful in the medical field? The answers to these questions can be found in this lesson on the applications of nuclear chemistry.

Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

11. Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

When you hear the term 'nuclear power,' what comes to mind? Do you know where that energy and power is coming from? In this lesson, we are going to zoom in on the nucleus of a helium atom to explain how something as small as a nucleus can produce an extremely large amount of energy.
