Ionic, Covalent, and Metallic
Ionic Bonding- a bond between a nonmetal and metal.
-Happens when an atom loses an electron
-Dissolves in water; doesn't melt; conducts except in a solid state
Example-LiF (Lithium Fluoride), NaCl (Sodium Chloride)
Covalent Bonding-a bond between 2 nonmetals
-Non polar covalent bond are "equal"
-Polar covalent bonds are "unequal"
-Happens when 2 atoms share an electron
-Low melting point; never conducts
Examples-CO2 (carbon dioxide), H2O (water)
Metallic bonds-bonds between 2 metals
-Happens when a positively charged nuclei is attracted to an electron
-High melting point; does not dissolve; always conducts
Example- Cu+Zn (brass)
