Question

The atomic orbitals developed using quantum mechanics are?

1) S, P, D, F
2) 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f
3) 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 5s, 5p, 6s, 6p, 7s
4) 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d, 5f, 6s, 6p, 6d, 6f, 7s, 7p

Answer 1

The correct sequence of atomic orbitals up to the seventh energy level is 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d, 5f, 6s, 6p, 6d, 6f, 7s, 7p.

Step-by-step explanation:

The atomic orbitals developed using quantum mechanics are classified by the principal quantum number and the angular momentum quantum number. The correct sequence of atomic orbitals including all possibilities up to the seventh energy level (assuming no typographical error in the options provided) is 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d, 5f, 6s, 6p, 6d, 6f, 7s, 7p. This includes the 's', 'p', 'd', and 'f' subshells and their corresponding orbitals with increasing principal quantum numbers.
