The electrostatic intraction between +ve ions and surrounding electron cloud that hold metal atoms together is called metalic bonding.

Explanation:

1. The lack of opp charged ions and lack of sufficient valance electrons to form a covalent bond necessiate the sharing of valance elctrons by more than 2 atoms.
2. So each atom contributes its valance electrons to the formation of -ve electron cloud.
3. These electrons are not associate witha perticular ion but are free to move among +ve metal ions in definit energy levels.
4. The metalic ions are held together by virtue of their mutual attraction for -ve electron cloud.
5. Metallic bond is an extesion of covalent bond to a large number of atoms.
