page 1 of 4 ANAT 11110 Lectures 4, 5, 6, & 7 Fall 2011 The Chemical Level of Organization I. Review of Basic Chemistry A. Atoms and molecules 1. Atomic structure a. Composition: protons (positively charged particles), electrons (negatively charged particles), and neutrons (uncharged particles) b. Atomic number: the number of protons in the nucleus c. Atomic mass: the number of protons and neutrons in the nucleus of an atom d. Elements (atoms with the same number of protons) and isotopes (atoms of an element with differing numbers of neutrons) e. Atomic weight: the average number of protons and neutrons in the nuclei of the various isotopes of an element 2. Chemical bonds a. Electrons and energy levels/electron shells b. Inert vs. reactive elements: dependent upon the number of electrons in the outer electron shell c. Ionic bonds (electrons are either 'accepted' or 'given away') i. Ions: cations (positive charge) and anions (negative charge) d. Covalent bonds (electrons are 'shared' between two different atoms) i. Types: nonpolar vs. polar covalent bonds e. Hydrogen bonds: intramolecular or intermolecular bonds
