Chemistry refresher for biology students

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 #bio1 #apbio #electrons #chemistrycat #periodictable
