Which statements about orbitals are correct?
Hints
- Three are standard quantum results; one misreads the shape of a p orbital.
- A p orbital is a single orbital that happens to have two lobes.
Show the answer
- A. An orbital describes a probability distribution, not a trajectory
- C. Degenerate orbitals fill singly before any pairs form
- D. Each orbital can hold at most two electrons
Why
Orbitals are probability clouds, cap at two electrons by Pauli, and fill singly first by Hund. The two lobes of a orbital belong to one and the same orbital.
