What experimental evidence supports the model of metallic bonding?
Yanka [14]
Metals conduct electricity and heat, indicating that the electrons are free to move. Metals are malleable, showing that atoms are not in fixed positions but can remain bonded even though they change their positions. In metallic bonding, atoms donate electrons to a pool and all the atoms share in the pool. No compounds are formed, but the atoms are bonded into a network.
