A nonmetal (or non-metal) is a biochemical component that frequently requires metallic characteristics. Materially, nonmetals tend to have moderately low melting and boiling points, and densities, are essentially inelastic if solid.
When a nonmetal bonds with a nonmetal the result is a covalent bond. A covalent bond is a chemical bond which includes the sharing of electron pairs among atoms. Water (H2O) and carbon dioxide (CO2) are examples of covalent bonds. In H2O, one oxygen atom joins with two hydrogen atoms.
However they are habitually poor conductors of heat and electricity chemically, they manage to have approximately powerful ionization energy, electron relationship, and electronegativity charges.
