Question

In nitrogen, aluminium, oxygen, calcium the correct order of

Paramagnetism is? And why....

Answer 1

Dear Student

Greater the number of unpaired electrons greater will be the amount of paramagnetism.

(i) Electronic configuration nitrogen will be 1s22s22p3 which means it has 3 unpaired electron.
(ii) ​Electronic configuration aluminium will be 3s23p1 which means it has 1 unpaired electron.
(iii)​Electronic configuration oxygen will be 2s22p4 which means it has 2 unpaired electron.
(iv) ​Electronic configuration calcium will be 4s2 which means it has 0 unpaired electron.

So the answer is
N > O > Al > Ca

Hope this helps :)
