Question

Which of the following is the correct order of energy levels of atomic orbitals?
(A) 1s < 2s < 2p < 3s<
(B) 1s < 2p < 3s < 3p< 2s
(C) 3p < 3s < 2p < 2s< 4s
(D) 1s < 2s < 3s < 2p< 3p

Answer 1

Option (a), 1s < 2s < 2p < 3s< is the correct answer.

An atom is made up of a nucleus. The electrons make up the rest of the atom and revolve in fixed orbitals.

Each orbital is different and has a specific quantum number. The letters s, p, d, f represent the angular momentum.
