Tossup

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 (10[1])these entities in the Hartree–Fock method for (-5[1])determining their coefficients; that method involves taking a linear combination of these entities. Spin multiplicity is maximized in the occupation of these entities according (10[1])to Hund’s rule. (10[2])The tetrahedral geometry (10[1])and identical bonds of methane are due (10[1])to the hybridization of four (10[1])of these entities, three of which have a characteristic dumbbell shape. (-5[1])For 10 points, the s, p, d, and f types of what regions surrounding the nucleus are occupied by electrons? ■END■ (10[2])

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”]
