Sir mai aapse ek baat poochna chah raha tha ki jo aap diamagnetic behaviour aur paramagnetic behaviour nikalte hai usme aapne kaha tha ki you can find para or dia mag. by calculating total no. Of electrons but sir kahi kahi ye fail bhi ho raha tha jaise last wala questions saare molecules me even no Of electrons hai but phir bhi kuch molecules diamagnetic hai aur kuch paramagnetic so pls make a video on my doubt as soon as possible....
