Chapter 23.1, Problem 23.1AFP

(a)

Interpretation Introduction

Interpretation:

The partial electronic configuration of $A{g}^{+}$ ion has to be written.

Concept introduction:

These elements are in Periods 5, so the general configuration is,

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

For the ions, we recall that $ns$ electrons are lost first.

(b)

Interpretation Introduction

Interpretation:

The partial electronic configuration of $C{d}^{2+}$ ion has to be written.

Concept introduction:

These elements are in Periods 5, so the general configuration is

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

For the ions, we recall that $ns$ electrons are lost first.

(c)

Interpretation Introduction

Interpretation:

The partial electronic configuration of $I{r}^{3+}$ ion has to be written.

Concept introduction:

These elements are in Periods 6, so the general configuration is

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

For the ions, we recall that $ns$ electrons are lost first.
