1. Names From Formulas - Simple Salts

2. Naming simple cations is easy:
Li+
lithium cation
Be2+
beryllium cation
Na+
sodium cation
Mg2+
magnesium cation K+
potassium cation
Ca2+
calcium cation
Rb+
rubidium cation
Sr2+
strontium cation
Cs+
cesium cation
Ba2+
barium cation
Al3+
aluminum cation
Ag+
silver cation
Cd2+
cadium cation
Zn2+
zinc cation
Ni2+
nickel cation

3. N3- O2- F- P3- S2- Cl- Se2- Br- I- He Ne Ar Kr Xe
Naming simple anions is only slightly more challenging. He Ne Ar Kr Xe
N3-
O2- F-
nitride
oxide
fluoride
P3-
S2-
Cl-
phosphide
sulfide
chloride
Se2-
Br-
selenide
bromide I-
iodide

4. Try naming these formulas with the names of the anions visible:
nitride - N3- oxide – O2- fluoride – F-
phosphide - P3- sulfide – S2- chloride – Cl-
selenide – Se2- bromide – Br-
iodide – I-
NaCl
sodium chloride
Cs3P
cesium phosphide
BaBr2
barium bromide
AlCl3
aluminum chloride
K2S
potassium sulfide
Ag2O
silver oxide
MgO
magnesium oxide
ZnS
zinc sulfide
Mg3N2
magnesium nitride
CdI2
cadmium iodide
AlN
aluminum nitride
NiF2
nickel fluoride

5. Do we ever specify the number of anions or cations?
No!
Try naming these formulas without the names of the anions visible:
NaCl
sodium chloride
K3N
potassium nitride
CaCl2
calcium chloride
Mg3N2
magnesium nitride
AlCl3
aluminum chloride
AlN
aluminum nitride
Na2O
sodium oxide
NiO
nickel oxide
CaO
calcium oxide
AgI
silver iodide
Al2O3
aluminum oxide
CdS
cadmium sulfide
