Answer:

Calcium :

Chemical formula of calcium = Ca

Valence of calcium = 2

Phosphate :

Chemical formula of phosphate = PO₄

Valence of phosphate = 3

We need to write the chemical formula of calcium phosphate

Using interching valency formula

calcium\ phosphate=Ca_{3}(PO_{4})_{2}calcium phosphate=Ca

3

(PO

4

)

2

Hence, The chemical formula of calcium phosphate is Ca_{3}(PO_{4})_{2}Ca

3

(PO

4

)

2
