The ions present in the solution of Na₃PO₄ are: 3Na⁺¹ and 1PO₄⁻³ there are 3 sodium ions (Na⁺¹) are present, these are cations (+). And 1 phosphate ion (PO₄⁻³) is present, this is anion (-), When these cations and ions meet together a compound is formed, in this case 3 sodium ions make a bond with 3 oxygens of phosphate and makes a compound of sodium phosphate.
Explanation: The combination of two or more atoms, from the same or different elements, creates a molecule. Compounds are a type of molecules made of atoms from different elements held together by chemical bonds.
