Write the formulas for the following ionic compounds: (a) copper bromide (containing the Cu1 ion), (b) man- ganese oxide (containing the Mn31 ion), (c) mercury iodide (containing the Hg21 ion), and (d) magnesium phosphate (containing the PO342 ion).

CuBr

Mn2O3

Hg2I2

Mg3(PO3)2

Explanation:

When writing the formula of an ionic compound, we use the exchange method.

The symbol of each element or ion is written with it's charge as a superscript. The charges are then interchanged, the signs are dropped and the figures are written as subscripts. This gives the formula of compound.
