Question

Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible?(1 point)

Metals have low electronegativity, so they are conductive because they pass charges easily.

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.

Answer 1

Conductivity is possible in metals because metallic bonds can shift due to the fact that valence electrons are held loosely and move freely.

WHAT ARE METALLIC BONDS:

• Metallic bonds are bonds that holds metals together. In metallic bonding, electrons are shared between positive metal ions.

• The electrons that flow in metals are delocalized, hence, are able to move freely.

• These free moving electrons are responsible for the high conductivity that metals exhibit.

Therefore, conductivity is possible in metals because metallic bonds can shift due to the fact that valence electrons are held loosely and move freely.
