Question
A d orbital has two planes that act as these regions because its azimuthal quantum number is two. For 10 points each:
[10m] Name these regions of space where a wavefunction goes to zero, meaning there is no chance an electron will be found there. They’re named in analogy to points where waves have no amplitude.
ANSWER: nodes [or nodal planes]
[10h] For a hydrogen atom, this atomic orbital instead has two radial nodes: one each at twice the Bohr radius and seven times the Bohr radius. In the ground state, sodium’s valence electron lies in this specific atomic orbital.
ANSWER: 3s [prompt on 3 or s]
[10e] This molecule’s lowest unoccupied molecular orbitals have two vertical planar nodes. This aromatic molecule is a six-carbon ring that allegedly resembles a snake eating its tail.
ANSWER: benzene [or C6H6 (“C-6-H-6”)]
