Vedclass · Answer

(D) The energy of an electron in a hydrogen-like atom depends on the principal quantum number $n$. For multi-electron atoms,it depends on the $(n+l)$ value.For $2p_x$,$2p_y$,and $2p_z$ orbitals,the values of $n = 2$ and $l = 1$ are the same.Since they have the same $(n+l)$ value,they are degenerate orbitals,meaning they have the same energy.Therefore,the energy of the $2p_y$ orbital is the same as that of the $2p_x$ and $2p_z$ orbitals.

The energy of an electron of $2p_y$ orbital is :
