These forces operate throughout the lattice. Metals are good conductors of heat. Delocalised electrons transmit the energy of vibrations of 1 positive ion to its neighbours. Metals are good conductors of electricity. Mobile delocalised electrons within the lattice.
Electrons flow in at one end, and the same number flow out the other end.
Metals are malleable and ductile. The distortion does not disrupt the metallic bonding. Metals are lustrous. Ionic Bonding Bonding between metals and non-metals . Metal atoms have a low number of valence electrons and a low electronegativity.
