Review: Naming and Writing Ionic and Covalent Compounds

In todays class we had a review for writing and naming ionic compounds. Listed below is a summary of the class :)!
Ionic Compound
-composed of two or more particles that must be oppositely charged
-electorstatic forces hold them together
-metal-->non-metal transfer

Example: Na^+ P^3-
=Na3P  (criss cross)
=Sodium Phosphide

Example: Fe^2+ S^2-                **use roman numerals when an element has more than one charge**
=FeO
=Iron(II)Oxide

Complex Anions
-group of atoms that act as one atom

Example:
a)zinc phosphate-->Zn3PO4
b)tin(II) permanganate--> Sn(MnO4)2
c)Pb(CO3)2--> lead(II) carbonate

Covalent Compounds
-share electrons
-non-metal with non-metal
**Diatomic molecules: H2, O2, F2, Br2, N2, Cl2, I2**
-use greek prefixes to indicate the nuber of atoms


Example:
a)CO2--> carbon dioxide
b)sulphur trioxide--> SO3
