Chapter 5, Problem 1CTQ

Which elements on the periodic table (other than H) are likely to form $\text{a}+1$ cation?

Interpretation Introduction

Interpretation: The elements on the periodic table other than hydrogen that forms $+1$ cation should be determined.

Concept introduction: Cations and anions are molecules with a net positive and negative charge. These molecules lost or gain their valance electron to acquire the net charge.

Explanation of Solution

In the periodic table, $+1$ charge is acquired by those elements which gain noble gas configuration after the loss of one electron. These elements are group I elements in periodic table. These elements are as follows:

  $\begin{array}{cccccc}\text{Li}& \text{Na}& \text{K}& \text{Rb}& \text{Cs}& \text{Fr}\end{array}$
