Answer

Explanation:

Step1: Determine the charges

Calcium ((Ca)) is in group 2 of the periodic table, so it forms (Ca^{2 +}) ions. Phosphate ((PO_{4})) is a polyatomic ion with a charge of (PO_{4}^{3-}).

Step2: Use the criss - cross method

To form a neutral compound, we need to balance the charges. The least common multiple of 2 and 3 is 6. So we need 3 (Ca^{2+}) ions ((3\times2 = 6)) and 2 (PO_{4}^{3 -}) ions ((2\times3=6)).

Answer:

(Ca_{3}(PO_{4})_{2})
