Answer:
electron sea model for metals suggest that valence electrons drift freely around the metal cations.
Explanation:
Explanation: In electron sea model, the valence electrons in metals are delocalized instead of orbiting around the nucleus. ... These electrons are free to move within the metal atoms. Thus, we can conclude that the electron sea model for metals suggest that valence electrons drift freely around the metal cations.
A. NO2 because the elements are both nonmetals.
