1. 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.

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. 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.

4. 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.

5. 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.

6. What is Atomic Mass? - Definition & Examples

Atomic mass is a characteristic of an atom that is a measure of its size. It is plays a major role in the chemical properties of elements. This article discusses atomic mass and how it is calculated.

7. 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.

8. 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.

9. Principles of Radiometric Dating

Radiometric dating is a method used to determine the age of rocks and other materials based on the rate of radioactive decay. Learn about three common types of radioactive decay: alpha decay, beta decay and gamma decay.

10. Radiometric Dating: Methods, Uses & the Significance of Half-Life

Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes. Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson.

11. Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

What causes a radioactive particle to decay? We'll never really know, but our best guess lies in probability. In this lesson, we are going to focus on the half-life, a way of measuring the probability that a particle will react.

12. Types of Radioactive Decay and Their Effect on the Nucleus

What is meant by the term 'radioactive'? In this lesson we will break down the three main types of nuclear decay particles and discuss their composition, their effect on the nucleus, and their applications.

13. 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.

14. 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.

15. Chromatography, Distillation and Filtration: Methods of Separating Mixtures

What are some ways that mixtures can be separated? Watch this video to explore several examples of ways you can separate a mixture into its individual components.

16. Gas Chromatography & Mass Spectrometry

Scientists interested in identifying the individual chemicals in a mixture use an instrumental method called gas chromatography mass spectrometry or GC-MS. Continue reading to learn about the ins and outs of this fascinating chemistry technique.
