Question 22 • 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 orbit specific atoms.
B
They both allow electrons to move from lower energy levels to higher energy levels.
C
They both involve ionization of some atoms so bonding can occur.
D
They both have localized electrons that move from atom to atom.

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.
