Question

which has more energy,3d or 4p? Explain​

Answer 1

Answer:

We say that the 4s orbitals have a lower energy than the 3d, and so the 4s orbitals are filled first. ... The electrons lost first will come from the highest energy level, furthest from the influence of the nucleus. So the 4s orbital must have a higher energy than the 3d orbitals.
