Is the order of filling orbitals the same as the order of increasing energy in orbitals, or is it different?
Please tell me if I am right or wrong:
Order of filling orbitals:
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, etc...
Orbitals in order of increasing energy:
1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d, 5f, 6s, 6p, 6d, 6f, etc...
I am pretty sure I got the second one wrong but I am not being able to find an answer anywhere
