To understand biology, you need to understand some basic chemistry. This is a refresher that walks through the major elements found in living things, the structure of an atom, atomic number/atomic mass, and how electrons populate the energy levels around an atomic nucleus. Start here before learning about the important bonds in biological molecules, such as covalent, ionic, and hydrogen bonds.
Use the chapters to jump topics:
00:00 Matter, elements, and the periodic table
04:31 Major elements found in living organisms
06:21 Components of an atom
09:03 Protons and neutrons, atomic number, and atomic mass
16:38 How electrons fill electron shells in at atom
20:10 Examples of how to fill electron shells based on the element
23:31 The valence electrons determine the chemical activity of an atom
25:52 Practice question
28:27 Carbon, the backbone of biological molecules
