State hund's rule.
choose one:
a. an attraction between two electrons occurs due to vibrations in the crystal lattice.
b. each electron goes into the lowest-energy orbital available.
c. the lowest-energy electron configuration of an atom has the maximum number of unpaired electrons, all of which have the same spin, in degenerate orbitals.
d. we cannot determine both the position and the momentum of an electron in an atom at the same time.
e. no two electrons in an atom can have the same set of four quantum numbers. f. electrons orbiting and protons within the nucleus of the atom have a balanced charge, excluding attraction to charged species.
