Question 34 • Chemistry - SC3210 A-CR

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

Explanation

Atomic orbitals and energy bands both describe allowed energy states for electrons. In either system, an electron can absorb energy and move from a lower-energy state to a higher-energy state. The electrons in a metal’s bands are spread throughout the crystal rather than localized around specific atoms, so choices A and C do not fit.
