1.All the valence electrons of the bonded metal atoms are shared in an electron sea.
2.The electron sea is able to move freely through the metallic structure.
3. The electron sea is localized between two metal atoms at a time.
4. The metal is held together by the attraction between the metal ion cores and the sea of valence electrons
