2) Metallic bonds involve the all-important "free electrons" which produce all of metals properties. These free electrons come from the outer shell of every metal atom in the structure. 

3) These electrons are free to move and so metals are good conductors of heat and electricity.

4) These atoms also hold the atoms together in a…
