- Metallic bonding occurs when you have a metal in the solid or liquid state. The s and p valence electrons of metals are loosely held. They leave their “own” metal atoms. This forms a "sea" of electrons that surrounds the metal cations.
2.in a metallic solid atoms are arranged in a lattice-like 3D structure where there is a regular array of metal cations surrounded by a sea of delocalised electrons. ... This means that the outer electrons are held more loosely than the inner electrons, as they do not feel the pull from the positive nucleus as much
