How do physical properties of nonmetals differ from the physical properties of metals?

The inter or intramolecular bonding forces affect the physical properties of the metals and nonmetals.

The bonding forces of the element in the periodic table get varied within the periods and groups. In the groups, more shells increase the shielding effects and in the periods, the repulsion among the electrons increases. These factors affect the behaviour of an atom during the process of making bonding or reactions. These are the reasons which make the most of the metals in the solid form and nonmetals in the liquid or gas forms.
