1. Which of the following best describes metallic bonding?
Sharing of electrons between two non-metal atoms.
Transfer of electrons from a metal to a non-metal atom.
Electrostatic attraction between positive metal ions and a 'sea' of delocalized electrons.
Attraction between oppositely charged ions in a crystal lattice.
