Chapter 9.2, Problem 9.3E

Interpretation Introduction

Interpretation:

The electronic configuration of $\text{Pb}$ and ${\text{Pb}}^{\text{2+}}$ has to be discussed via Lewis electron-dot symbols method.

Concept introduction:

Lewis electron-dot symbols.

All stable molecules attain the noble gas and octet arrangement.  So that molecule is more stable and less reactive nature.

$\text{Z}{\text{= 25, so Mn}}^{\text{2+}}$ would have 23 electrons. Transition metals lose the ns electrons first.

According to Octet rule eight electrons in the outer most shell that atoms is most stable arrangement in other atoms have less than eight electrons.
