Write the formula for: Magnesium phosphate
Question
Write the formula for: Magnesium phosphate
Solution
The formula for Magnesium Phosphate is Mg3(PO4)2.
Here's how you get to that:
-
Identify the symbols for Magnesium and Phosphate from the periodic table, which are Mg and PO4 respectively.
-
Determine the charges of each. Magnesium (Mg) is a metal and has a charge of +2. Phosphate (PO4) is a polyatomic ion with a charge of -3.
-
Balance the charges. To do this, you need three Magnesium ions to balance with two Phosphate ions.
So, the formula becomes Mg3(PO4)2.
