KNO3
why would the formula for potassium nitrate be KNO3 If the nitrate has three of its self ( NO3- ). Would it not be K3NO3 so that the charges are neutral?

Because each ion has the same, but opposite charge:
K+ and NO3-, therefore the compound is neutral as the + and - cancel.

The "-" can be thought of as being on the NO3 as a whole. So there is only one - charge.
