Answer: 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.
