Round 14: Tossup 18

One form of these entities is often analogized to “onion skin,” where the empty space between layers represents these entities’ radial nodes. Slater-type functions represent these entities in the Hartree–Fock method for determining their coefficients; that method involves taking a linear combination of these entities. Spin multiplicity is maximized in the occupation of these entities according to Hund’s rule. (10[1])The tetrahedral geometry and identical bonds of methane are due to the hybridization of four of these entities, three of which have a characteristic dumbbell shape. For 10 points, the s, p, d, and f types of what regions surrounding the nucleus are occupied by electrons? ■END■

ANSWER: atomic orbitals [accept s orbitals or p orbitals or d orbitals or f orbitals or hybrid orbitals; accept orbital hybridization; accept linear combination of atomic orbitals; accept Slater-type orbitals; prompt on subshells or energy levels; reject “molecular orbitals”]
