The metallic bond is the attraction between the shared electrons and the protons in each atom’s nucleus a metal cation and a nonmetal anion a metal anion and a nonmetal cation a metal cation and the shared electrons that surround it

a metal cation and the shared electrons that surround it

Explanation:

Metallic bonding is the type of chemical bonding occurs between the atoms of a metals.In this type of bonding arises due to electrostatic interaction between the electron cloud of de-localized electrons with positively charges metal ions.

These de-localized electrons are the valence electrons of metal atoms which are shared between them.

A metal cation and a nonmetal anion are bonded by ionic bonding.
