Chapter 4.3, Problem 1QQ

Interpretation Introduction

Interpretation:

Identification of stable electronic configurations among the given options.

Concept Introduction:

Electronic configuration of an atom is a shorthand method of writing the location of electrons in the atom.  The valence electron configuration of the noble gases is considered as the most stable of all valence electron configurations.  Except Helium, all other noble gases possess ${\mathrm{ns}}^{2}n{p}^6$ valence electron configurations, where “n” has the maximum value found in the atom. All these gases have completely filled “s” and “p” orbital configuration.
