Document Summary

Electrons, particularly valence electrons play a fundamental role in chemical bonding. When electrons combine to produce compounds, they are attempting to achieve a full. Chapter 10 questions: 3,4,11,17, 18,21, 22b, 59, 62, 141. Lewis symbols: this is a way of representing the valence electrons in an element. Electrons can be transferred from one atom to another to make ions. The atoms are then help together by coulombic forces in an ionic bond. More often, the only way an atom can gain electrons is by sharing. It does not include the inner shell electrons. It does not include the spin of e-s. These are the combination of lewis symbols that represent the sharing or transfer of electrons in a molecule. Normally they are in crystals where one anion (negative) is attached to several cations. Electrical neutralist means the total number of each ion is the same.
