14. A molecule is composed of two non-metals
A molecule is composed of two non-metals. What is an ionic compound composed of? (Type I )

15. A metal and a non-metal

16. Ionic compounds form when a positive metallic ion and a negative non-metallic ion form and are attracted to each other. The compound has no charge.

17. Ions form when atoms gain or lose electrons
Ions form when atoms gain or lose electrons. These ions combine to form compounds.

18. Naming ionic compounds
You name compounds almost the same as molecules. There are only a few differences.

19. The main difference is that you do not use prefixes!
Let’s try some and see how it goes.

20. potassium chloride Notice there is no prefix being used.
What do you call the ionic compound KCl ?
potassium chloride
Notice there is no prefix being used.

21. magnesium chloride Still no prefix!
What do you call the ionic compound MgCl2 ?
magnesium chloride
Still no prefix!

22. What is CaSO4 ?
Calcium Sulfate,
also known as plaster of
paris.

23. What would you call
NH4NO3?
ammonium nitrate

24. FeO is called?
iron oxide

25. iron oxide Fe2O3 is called ?
But wait, how could there be two different iron oxides with different formulas?

26. FeO becomes iron (II) oxide
In order to distinguish between the two, you put the charge of the cation (iron) in roman numerals in parenthesis immediately behind the word iron.
FeO
becomes
iron (II) oxide

27. Fe2O3 becomes iron (III) oxide

28. CuO is called
Copper (II) oxide

29. Cu2SO4 is called
Copper (I) sulfate
