Question 40 • Chemistry

Which statement explains how the bands in the crystal of a metal are like atomic orbitals?

Answer
A
They both have localized electrons that move from atom to atom.
B
They both involve ionization of some atoms so bonding can occur.
C
They both have localized electrons that orbit specific atoms.
D
They both allow electrons to move from lower energy levels to higher energy levels.

Explanation

Atomic orbitals and energy bands both describe allowed electron energy levels. Electrons can absorb energy and move from a lower-energy state to a higher-energy state in either case, so the best choice is “They both allow electrons to move from lower energy levels to higher energy levels.” In a metal, electrons in bands are generally spread throughout the crystal rather than localized around specific atoms, which rules out A and D.
