Question

Which of the following atoms is paramagnetic?

• A. $Zn$
• B. $N$
• C. $Ca$
• D. $Sr$

Answer 1

The correct option is B $N$

If there are unpaired electrons in an atom, they will cause an attraction to an applied magnetic field which shows the paramagnetic behavior of that atom.
Electronic configuration of $N:$ $1s^{2}2s^{2}2p^3\Rightarrow$ p subshell is not filled which led to unpaired electrons.
$\because$ $N$ has unpaired electrons, thus it is paramagnetic.
