Interpretation:
The name of Mg(BrO4)2 is to be stated.
Concept introduction:
Most of the chemical compounds exist as a polyatomic ion and the ratio of positive to negative ions present in the substance is expressed as formula of ionic compound. The formula of a chemical compound is given by the lowest whole number ratio of ions in the compound and it is called as a formula unit. Some elements form monoatomic ions having different charges and to differentiate the two ions, size of the charge of ions is included when naming the ion. For group 1A, 2A, 5A-7A elements the charge is not included while naming the ion. In common, the charge is given in the name of an ion only when the ions of an element display more than one charge which is common. In other words, when an ionic compound having a metal that can exist in more than one ionic charge, is named the charge of metal atom should be included in the compound name.

Answer to Problem 15PE
The chemical name of the compound Mg(BrO4)2 is magnesium perbromate
Explanation of Solution
In polyatomic compounds, the number of protons and the number of electrons will be the same for a neutral atom. This results in no net charge on the atom (i.e., positive or negative). The key steps while giving the chemical formula to the ionic compounds are ; formulas of individual ions is written, and this is followed by balancing the charge of ions to get total charge of zero. Thus, Mg(BrO4)2 is named as magnesium perbromate. The charge neutrality is given as follows;
= 1 Mg2+ ion and 2 BrO4- ion
Thus, the name of Mg(BrO4)2 is stated.
