How many unpaired electrons are present in the ground state of an atom from each of the following groups?
Paha777 [63]

Explanation:

General electronic configuration for the given groups are as follows.

For 4A(14) : ns^{2}np^{4}

This means that there are 4 unpaired electrons in group 4A(14).

For 7A(17) : ns^{2}np^{5}

So, there are 7 unpaired electrons present in group 7A(17).

For 1A(1) : ns^{1}

Hence, there is only one unpaired electron present in group 1A(1).

For 6A(16) : ns^{2}np^{4}

So, there are 6 unpaired electrons present in group 6A(16).
