I am studying chemistry in High School and I am studying my ions(Because I failed too in the beginning, oops) and I have a question on this reasoning: In Phosphate(PO4), it has a charge of -3. The only way for this to make sense is if half the atoms of oxygen are positive and half are negative bring a positive charge of 4 and negative charge of -3 along with phosphorous being -3. Meaning that there is a total of Negative charge of 7 and positive charge of 4 leaving the total charge of the ion of -3. How come this happens?
