Textbook Problem

Identify a cation of a first series transition metal that is isoelectronic with each of the following.

(a) Fe3+

(b) Zn2+

(c) Fe2+

(d) Cr3+

(a)

Interpretation Introduction

Interpretation:

The cation which is isoelectronic with Fe3+ has to be identified.

Concept introduction:

  • The electron configuration tells us in which orbitals the electrons for an element are located.
  • Isoelectronic is described as the two or more molecule with same number of valence electrons and the same structure.
Explanation

The electronic configuration of iron is [Ar] 3d64s2. The electronic configuration of Fe3+ is [Ar] 3d5

(b)

Interpretation Introduction

Interpretation:

The cation which is isoelectronic with Zn2+ has to be identified.

Concept introduction:

  • The electron configuration tells us in which orbitals the electrons for an element are located.
  • Isoelectronic is described as the two or more molecule with same number of valence electrons and the same structure.

(c)

Interpretation Introduction

Interpretation:

The cation which is isoelectronic with Fe2+ has to be identified.

Concept introduction:

  • The electron configuration tells us in which orbitals the electrons for an element are located.
  • Isoelectronic is described as the two or more molecule with same number of valence electrons and the same structure.

(d)

Interpretation Introduction
