Statement : The 3p-orbital has higher energy level than 3s in `He^(+)` ion.
Explanation: The energy of an orbital depends upon n and l.

In this question has statement I and statement II of the four choice given after the statement choose the one that best describes the two statements Statement-Number of waves in an orbit of atom is equal to number of that orbit. Statement-I The 3p orbital has higher energy level than 3s in He^+ ion. Statement-II The energy of an orbital depends upon n and l

4s orbitals has less energy than 3d orbital

4s orbitals has less energy than 3d orbital

4s orbitals has less energy than 3d orbital

The energy level for He^(+) ion atom depends on :

Which has higher energy 3d or 4s orbital why?
