Bonding
Ionic Bonds - Formed by the transfer (loss or gain) of electrons - Formed between a metal and a non-metal - A salt is an ionic compound Properties of Salts: Hard, High Melting Point and Brittle

Covalent Bonds - Formed by sharing electrons - Formed between two non-metals

Octet Rule - Atoms tend to gain, lose or share electrons in order to reach an octet (a full set of 8 valence electrons).

Metallic Bond - Formed when metals donate all their valence electrons to a "sea of electrons" that are free to move around. - Formed between two metals Properties of Metals: Ductile, Malleable, Good conductors of heat and electricity
