There are lots of terms in chemistry that can be easy to mix up: atoms, molecules, compounds, mixtures, and more. In this lesson, we'll go through some of the basics of atoms and molecules, and define all of the important terms you need to know.

Overview of Chemical Bonds

2. Overview of Chemical Bonds

Learn about the most common kinds of chemical bonds: ionic, covalent, polar covalent, and metallic. Discover how they form and why they hold together. Take a quiz and see how much knowledge you've held onto.

Organic Molecules: Functional Groups, Monomers & Polymers

3. Organic Molecules: Functional Groups, Monomers & Polymers

Though life on Earth is incredibly diverse, all of it is built upon the same basic molecular structures. In this lesson, we'll look the basic building blocks of life and see how functional groups, monomers and polymers build up organic molecules.

ATP: Definition & Molecules

4. ATP: Definition & Molecules

ATP is the molecule that fuels life. It is where our cells get the energy needed to perform their tasks. This lesson will define ATP, explain its structure, and briefly outline how it works.

What is a Cell Membrane? - Definition, Location & Facts

5. What is a Cell Membrane? - Definition, Location & Facts

In this lesson, we'll discuss what a cell membrane is and its location. We'll also examine the cell membrane's functions, its components and structure, and its characteristics.

The Cell: Structure & Function

6. The Cell: Structure & Function

The cell is a small, but complex structure. Take a look inside the outer plasma membrane of a cell and discover the functions of some common cellular components, including the nucleus, endoplasmic reticulum, Golgi apparatus and mitochondria, in this lesson.
