Chapter 7.4, Problem 2RC

Interpretation Introduction

Interpretation:

Given the four different transitions ions are given in the statement and which ions have largest unpaired electrons it is respective shells, this configuration need to be identified.

Concept Introduction:

Electronic configuration: The electronic configuration is the distribution of electrons (e^-) of a given molecule or respective atoms in atomic or molecular orbitals.

Aufbau principle: This rule statues that ground state of an atom or ions electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels. If consider the 1s shell is filled the 2s subshell is occupied.

Hund's Rule: The every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
