Which of the following best describes metallic bonds?

• Metallic bonds involve a sea of delocalized electrons shared among metal atoms.
• Metallic bonds are formed by the transfer of electrons from one atom to another.
• Metallic bonds consist of tightly bound pairs of electrons between two atoms.
• Metallic bonds are characterized by localized electrons that do not move freely.

Which of the following best describes metallic bonds?
