Question

Which is true of the electron sea model?

a. Metallic atoms are present in a "sea" of negatively charged atoms.
b. Valence electrons are able to move easily among the metallic cations
c. It results in the substance being very brittle and not easily deformed.
d. Heat and electricity are easily carried by the cations from one region to another.

Answer 1

The correct statement regarding the electron sea model is that valence electrons move easily among metallic cations, allowing metals to conduct heat and electricity.

Step-by-step explanation:

The correct statement regarding the electron sea model is: b. Valence electrons are able to move easily among the metallic cations. This model suggests that mettallic atoms are surrounded by a sea of electrons that can move freely. These delocalized valence electrons allow metals to conduct electricity and heat efficiently. Unlike ionic compounds that are brittle, this model explains why metals are not brittle but are malleable and ductile. The electron sea model does not make the substance brittle nor does it suggest that the cations carry heat and electricity; it is actually the motion of the electrons that facilitates this.
