Chapter 23, Problem 23.2P

(a)

Interpretation Introduction

Interpretation:

The general electronic configuration of a transition elements in period 5 has to be written.

Concept introduction:

The element in the periodic table and count its position in the respective transition series. These elements are in Periods 5 and 6, so the general configuration is

  $\left[noblegas\right]n{s}^2\left(n-1\right)d^x.$

The ions, we recall that ns electrons are lost first.

(b)

Interpretation Introduction

Interpretation:

The general electronic configuration of a transition elements in period 6 has to be written.

Concept introduction:

The element in the periodic table and count its position in the respective transition series. These elements are in Periods 5 and 6, so the general configuration is

  $\left[noblegas\right]n{s}^2\left(n-1\right)d^x.$
