Question

Which orbital has more energy 3s, 3p, 4s​

Answer 1

Answer:

3s has more energy

Answer 2

If two orbitals have the same value of (n+l), the orbital with lower value of n will have the lower energy . Since , the (n + l) value of 3d orbital is greater than 4s orbital . That's why 3d orbital has more energy than 4s orbital
