Question

find out the difference in number of angular nodes and number of radial nodes in the orbital to which last electron of chromium is present​

Answer 1

Chromium las electron presents in 3d-

orbital for which1 = 2.

So, no.of radialnode=n—-1-1

=3-2-1=0

and no. of angular node =1=2

Therefore, the difference in number of angular nodes and the number of radial nodes is 2.
