Answer:
According to the subshells, the  ns subshell has a sphere-like shape, and on average, lower energy than the rest of the subshells on the same quantum level Â
The np subshell has two lobes opposite the origin, and on average has more energy than a ns subshell since it has one more angular node, and thus  np electrons are less core-like (and further away from the nucleus).
n d orbitals have five spatial orientations:
and n f orbitals have seven spatial orientations
The energies are on average in increasing order for the same energy level , n as follows,
nS < nP < nD < nF
