Chapter 12, Problem 53E

Interpretation Introduction

Interpretation:

The formula of a compound that is formed by the combination of ${\text{Rb}}^{+}$ and ${\text{Se}}^{2-}$, is to be stated.

Concept Introduction:

The nucleus loosely holds the valence electrons of metal atoms. Therefore, these valence electrons are easily removed to form a cation. A metallic bond forms by the attractive force between positively charged metal ions and negatively charged valence electron.
