Question

metallic bonds are responsible for many properties of metals, such as conductivity. why is this possible? (1 point)
two metals bonded together are going to be more conductive than a metal bonded with a nonmetal.
an attraction between a positive charge and a negative charge is created
the bonds can shift because valence electrons are held loosely and move freely.
metals have low electronegativity, so they are conductive because they pass charges easily

Explanation:

In metallic bonding, metal atoms release their valence - electrons which form a "sea" of delocalized electrons. These electrons can move freely throughout the metal lattice. When an electric potential is applied, the free - moving electrons can carry the electric current, which is responsible for the conductivity of metals.

Answer:

The bonds can shift because valence electrons are held loosely and move freely.
