Document Summary

Topics covered: 7. 1 ionic bonding, 7. 2 covalent bonding, 7. 3 lewis symbols and. Compounds composed of ions are called ionic compounds (or salts) Ionic bonding the electrostatic attraction that holds oppositely charged ions together in an ionic compound. Atoms can also make chemical bonds by sharing electrons equally between each. Nonmetal atoms frequently form covalent bonds with other nonmetal atoms other. The a measure of the tendency of an atom to attract electrons (or electron density) towards itself. Increases across a period (left to right) Decreases down a group (top to bottom) Electrons shared equally in a bond is called a pure covalent bonds. When the atoms linked by a covalent bond are different, the bonding electrons are shared, but no longer equal. This unequal distribution of electrons is known as a polar covalent bond , characterized by a partial positive charge on one atom and a partial negative charge on the other.
