How many pairs of electrons are present in the valence shell of a neutral ground-state nitrogen atom?
Select one: a. 0 b. 1 c. 2 d. 3
Nitrogen - atomic number = 7
Electronic configuration - 1s2 2s2 2p3
valence shell is the outermost shell of every element.
so , there are 5 electrons in the outermost shell of Neutral Nitrogen atom.
but if we see as electron pair , there are only two electron pairs.
option(c) is correct
