Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible?

A. The bonds can shift because valence electrons are held loosely and move freely.
B. An attraction between a positive charge and a negative charge is created.
C. Metals have low electronegativity, so they are conductive because they pass charges easily.
D. Two metals bonded together are going to be more conductive than a metal bonded with a nonmetal.

The correct answer is A. The bonds can shift because valence electrons are held loosely and move freely.

In metallic bonding, valence electrons are not tightly bound to individual atoms; instead, they form a "sea of electrons" that are free to move throughout the metal structure. This mobility of electrons allows metals to conduct electricity and heat effectively.
