Types of Bonds

A metallic bond is a bond between ________.

• nonmetals

What do electrons do in a metallic bond?

• They stay on the metal atom.

• They are transferred from atom to atom.

• They form a covalent bond with another atom.

• They float around freely.

What is meant by the term "sea of electrons"?

• It's what we call all the free floating electrons in a metal.

• It's what we call electrons that are floating in a liquid.

• It's the total number of electrons in a metal atom.

• It's the total number of electrons in the ocean.
