Chapter 3.6, Problem 3.12PP

Interpretation Introduction

(a)

Interpretation:

The formula of the compound forms when sulfate anion combines with magnesium cation should be written.

Concept Introduction:

Elements with similar electronic configurations are categorized into similar group in periodic table. So elements in the same group can form ions with similar charges. There is a relationship between the group number and the charge of the stable ion formed by an element of main group. Elements in 1A,2A and 3A forms cations with a charge equals to its group number. Elements in groups 5A,6A and 7A form anions with charge equals to (8-group number).

Charge of transition metals and some of main group elements cannot be predicted as they form more than one type of cation.
