Question 2 • Chemistry

Which is a characteristic of the electron sea model for metallic bonding?

Answer
A
Electrons are in fixed positions in the orbitals.
B
Electrons flow easily between metal nuclei.
C
Atomic nuclei are arranged in an irregular pattern.
D
Molecular orbitals overlap to produce bands.

Explanation

In the electron sea model, metal atoms contribute delocalized electrons that can move throughout the metal among the positively charged nuclei. This mobile “sea” of electrons explains why electrons flow easily in metals. The nuclei are generally arranged in an orderly lattice, not an irregular pattern.
