Question

Why d-orbital does not exist in 2nd energy level ?​

Answer 1

Answer:

In the ground state for each energy level: In the 2nd energy level, electrons are located only in the s and p sublevels, so there are no d orbitals. In the 1st energy level, electrons occupy only in the s sublevel, so there is no d sublevel.
