Statement (S): The magnetic moment of

\mathrm{Mg}

-atom is more than

\mathrm{K}

-atom as the former has two electrons in outermost shell.

Explanation (E): The magnetic moment of

\mathrm{N}

-atom is more than magnetic moment of

\mathrm{O}

-atom and former has more number of unpaired electrons.

View answer and explanation

Correct option: B

S is wrong but E is correct

Option B (S is wrong but E is correct) is correct because the magnetic moment depends on unpaired electrons, and the explanation about N and O is accurate.
