What is the Cation to Anion Ratio for Ionic Compounds?

In summary, the conversation discusses determining the ratio of cations to anions for various ionic compounds, including potassium chloride, calcium fluoride, aluminum oxide, calcium oxide, and strontium chloride. The speaker expresses difficulty in chemistry and asks for help in finding the answers. The concept of cations and anions and their charges is mentioned as a way to determine the ratio.

Hey everyone,
Im pretty terrible in Chemistry, and I am stuck on something that's probably easy and obvious:
Determine the ratio of cations to anions for the following ionic compounds.
a. Potassium chloride.
b. Calcium Fluoride.
c. Aluminum oxide
d. calcium oxide.
e. Strontium chloride.

If somone could provide me with some information on how I can come about the answers, It would be greatly appreciated.

Thanks,
Lou

It would probably help to write out the chemicals like this instead,
KCl
CaF2
Al2O3
CaO
SrCl2

Cations have a positive charge, anions have a negative charge, over all, the compound has a neutral charge.
