PLEASE ANSWER FAST This picture is a representation of the "Sea of Electrons" model of metallic bonding. Which of the following best explains how the Sea of Electrons model explains the properties of metals?
1. Metals conduct electricity easily because each electron stays bound to one metal atom
II. Metals conduct electricity easily because their electrons flow between their many different
atoms
III. Metals are malleable because their electrons are stationary within their atoms, which
prevents them from being deformed and bent
IV. Metals are malleable because their electrons can move and be deformed, which allows the
metals to be deformed and bent
