nomenclature
Nomenclature is a way to name compounds. The names can be found on the periodic table, but when naming compound there are other rules that you have to follow.
1.When you have metal and a non-metal, the metal comes first, followed by the non-metal. The non-metal endings changes to "ide".
2. If there are two non-metals, you must use the following prefixes:
1: mono-
2 :di-
3 :tri-
4 :tetra-
5 :penta-
6 :hexa-
7 :hepta-
8 :octa-
9 :nona-
10 :deca-
Rule 3. For Poly atomic ions you need look at the chart which is usually provided.
Scroll down and click on poly atomic ions for the list.
Rule 4. When you have a metal and a non-metal you have an ionic compound then you need to follow the cross over rule.
Writing Ionic Compound Formulas: Cross over Method
Step 1: Find the charge on each piece
Step 2: Cross over charge #’s to quantity #’s.
Ex. Magnesium Flouride
Mg2 + F1- = MgF2

Basic Example
Al = Aluminium
Ca = Calcium
Ba = Barium
Cl = Chlorine
