Chapter 1, Problem 1.3P

Interpretation Introduction

Interpretation:

The ground-state electron configuration of the nitrogen atom is to be written. Valence electrons and core electrons in nitrogen are to be stated.

Concept introduction:

The arrangement of electrons in atomic orbitals is called the atom’s ‘electron configuration’. The most stable electron configuration of an element is called the ‘ground state’ configuration. Valence electrons are the electrons occupying the highest energy shell while core electrons are the electrons occupying the remaining lower energy shells of an atom.
