Chapter 3.4, Problem 3.10P

(a)

Interpretation Introduction

Interpretation:

The name of the ion ${\text{S}}^{\text{2-}}$ has to be given.

Concept Introduction:

Naming of cations:  The word “ion” is added after the name of the metal cation to differentiate it from the neutral atom.  Cations of the main group metals take the name of the element from which they are formed.

Example:  The name of the cation of sodium is sodium ion.

Rules for naming two different cations of same metal:

Method 1:  The name of the cation is followed by a Roman numeral in parentheses to indicate its charges.

Method 2:  The suffix “-ous” is used for the cation that has the lesser charge, and the suffix “-ic” is used for the cation that has the higher charge.  These suffixes are added generally added to the Latin names of the elements.

Naming of anions:  In anions, the ending of the name of element is replace by the suffix “-ide”.

Example:  The name of anion of chlorine is chloride.
