The valence electrons of metals are weakly attracted to the parent nuclei so the electrons break free and float. The moving electrons form a electron negative blanket that binds the positive nuclei together forming a metallic bond.

Explanation:

A metallic bond can be described as a bond that is formed between metals atoms. In such a kind of bond, the valence electrons form an electron cloud as they freely move between orbits of different atoms. An electrostatic force is generated due to these electrons and the positively charged nuclei (cations).

This unique kind of metallic bonding is responsible for giving a wide number of properties to the metals.
