IONIC: Always solid at room temperature, non-metal bonded with a metal, involves ions (charged particles), negatively charged ions attracted to positive ions, full outer shells achieved by transferring electrons, very high melting points, conduct electricity when melted or dissolved but NOT when solid, COVALENT: shared pair of electrons, non-metal bonded with non-metal, Can form discrete molecules or giant networks, full outer shell achieved by sharing outer electrons electrons, can be solid, liquid or gas at room temperature, Molecules have low melting points, Network structures have high melting points, Never conduct electricity in any state,
