Document Summary

This unit will contribute to your basic understanding of the nature and chemistry of biologically relevant molecules. Unit activities: read the following sections in chapter 2 of your textbook. The summaries and/or guidelines provided with the reading list will direct you to the examinable parts of each textbook section: section 2. 1: elements and atoms. From this section, it is important to gain an understanding of how electrons, protons, and neutrons come together to form atoms. You should also include in your notes definitions of the terms element, atomic number, and mass number: section 2. 2: chemical bonds and reactions. This section describes important chemical bonds including: non-polar and polar covalent bonds, ionic bonds, and hydrogen bonds. The key idea is that the goal of chemical bonds is for each atom to contain a full complement of electrons in the outer shell by either gain or loss of electrons, or sharing of electrons.
