which shells (also known as blocks) do we use for the quantum mechanical orbitals? r, h, s, and c s, p, d, and f 1, 2, 3, and 4 a, b, c, and d
Answer
Brief Explanations:
In quantum mechanics, the common shells (blocks) for orbitals are s, p, d, and f. These represent different shapes and energies of electron - orbitals around the nucleus.
Answer:
S, P, D, and F
