Question

Which among the following sub shell has the highest energy? 2s, 4s, 3d​

Answer 1

Answer:

          3d

Explanation:

         3d orbital has greater energy than 2s, and 4s because its n+l value is (3+2=5) which is more than n+l value for 2s (2+0=2), 4s,(4+0=4) orbital. If two subshells or orbitals have the same n+l value, the subshell or orbital with a lower n value will have lower energy.
