Exploring Chemical Bonding Concepts

What is the primary characteristic of metallic bonds?

• They are found only in non-metallic elements.

• They involve the sharing of electron pairs between atoms.

• They are formed by the transfer of electrons from one atom to another.

• They involve a sea of delocalized electrons moving among positive ions.
