1. SINGLE VALENT METAL IONIC COMPOUNDS

2. Writing Names Write the name of the metal
Write the name of the non-metal changing the ending to ide

3. Examples SrF2 Strontium flouride Li3P Lithium Phosphide
Ca3N Calcium nitride
ZnS Zinc sulphide
K2O Potassium oxide

4. Writing formula The symbol for the metal is always written
first followed by the symbol for the
non-metal
To determine the number of ions of each
element, find the least number of each
such that the total positive charge = the
total negative charge

5. Examples Potassium Chloride K+1 Cl-1
You Just need one of each to make a neutral molecule
KCl

6. Calcium Iodide
Ca I-1
I-1
CaI2

7. Sodium Phosphide
Na P-3
Na+1
________________
Na3P

8. Aluminum Nitride
Al N-3
We just need 1 of each
AlN

9. Aluminum Oxide
Al O-2
O-2
