Chapter 8, Problem 8.70QP

Interpretation Introduction

Interpretation:

The reason, why Group 1B elements are more stable than Group 1A elements even though they seem to have the same outer electron configuration $n{s}^1$has to be explained.

Concept Introduction:

The ionization energy is the minimum energy required to remove the electron from an isolated atom which is in the gaseous state results to give gaseous ion with one positive charge.

Group 1A in the periodic table contains 1 valence electrons and the outer electronic configuration of noble gases is $n{s}^1$.

Transition elements contain either d subshell which are incomplete or that can form cations having incomplete d subshell.
