Question

Name the ions present in Calcium Phosphate ________

Answer 1

The compound $C{a}_3(P{O}_4{)}_2$ is the molecule Calcium Phosphate.

Calcium is a +2 cation ${Ca}^{+2}$

Phosphate is a -3 polyatomic anion ${P{O}_4}^{-3}$

It takes three +2 calcium ions to balance with two -3 phosphate ions in order for the ionic charges to be equal an opposite.
