Chapter 12, Problem 20E

Interpretation Introduction

(a)

Interpretation:

The noble gas having identical configuration to ${\text{Se}}^{\text{2}-}$ is to be stated.

Concept introduction:

A representation of filling of electrons in orbitals in a systematic manner is known as electronic configuration. The pattern of filling of electrons is based on three principles that are Aufbau’s principle, Pauli-exclusion principle, and Hund’s rule.

Interpretation Introduction

(b)

Interpretation:

The noble gas having identical configuration to ${\text{Br}}^{-}$ is to be stated.
