Question

write the electronic configuration of chromium.write the value of n and l for its electron in the valence shell how many unpaired electrons are present in it

Answer 1

Hey there!!

Electronic configuration of chromium is :
◆ Cr => 1s2 2s2 2p6 3s2 3p6 3d5 4s1 .

This configuration is most stable because we know that half filled orbit and full filled orbit are more stable configuration.

There are 11 paired electrons and 2 unpaired electrons..

=>As it contains unpaired electrons so it's paramagnetic in nature
