What are non metals?
A nonmetal is a chemical element that mostly lacks the characteristics of a metal. Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density. A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity.
Chemical properties of non-metals
1) Nonmetals are poor conductors of heat and electricity. Graphite and Gas carbon are exceptions.
2) Unlike metals, nonmetals aren’t malleable and ductile.
3) Nonmetals react more with metals than with nonmetals.
