Chapter 3.2, Problem 3.3P

Interpretation Introduction

(a)

Interpretation:

The spheres which represented the S and S^2- should be determined.

Concept Introduction:

There are two types of ions said to be cations and anions.

The positively charged ions formed by loss of electrons is said to be cations whereas the negatively charged ions formed by gaining electrons is said to be anions.

Adding electrons to an atom increase its size. Removing electrons from atom reduce it size.
