1. Is it Ionic or Covalent???

2. Ionic: transfer of e-
High Melting Point, STRONG bond, requires IONS, charges equal zero, conduct electricity when aqueous
Covalent: Share e-
Low(er) Melting Point, does NOT conduct electricity, NO ions, NO charges, “flexible”/weak(er) bond

3. Starts with a Metal OR NH4 (Ammonium)
Ionic:
Starts with a Metal OR NH4 (Ammonium)
Covalent:
Starts with a Non-Metal, contains prefixes
