Question

Number of degenerated orbitals

Answer 1

$\mapsto$ Number of degenerate orbitals in a level of H-atom having En=Rh9 : 3rd orbit of H-atom having 1s,2s,2p,3s,3p,3d orbitals . ∴ Degenerate orbitals =1(3s)+3(3p)=5(3d)=9.

Answer 2

Number of degenerate orbitals in a level of H-atom having En=Rh9 : 3rd orbit of H-atom having 1s,2s,2p,3s,3p,3d orbitals . ∴ Degenerate orbitals =1(3s)+3(3p)=5(3d)=9.
