Which is true of the model of bonding shown in this figure? Your

Metallic atoms are present in a “sea” of negatively charged atoms.

Valence electrons are able to move easily among the metallic cations.

It results in the substance being very brittle and not easily deformed.

Protons are easily carried by the cations from one region to another.
