Notes

Metallic Solids are orderly collection of positive ions surrounded by and held together by free electrons, each metal atoms denoting one or more electrons. The Metallic bonds spread over the entire crystal. The bonding is not directional. The metals are good conductor of heat and electricity. Metals like sodium crystallise in simple cubic lattice.
