Here's how to break down the formula:

* Fe represents the element Iron.

* (II) indicates the Iron ion has a +2 charge.

* PO₄ represents the phosphate ion, which has a -3 charge.

* To balance the charges, you need three Iron(II) ions (3 x +2 = +6) and two phosphate ions (2 x -3 = -6).

Therefore, the final formula is Fe₃(PO₄)₂.
