Answer:
In chemistry, 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.

Answer:
Non-metals are not ductile and malleable. Excluding graphite, all non-metals are bad conductors of electricity and heat. They gain electrons to form negative ions when they react with metals. Non-metals form hydrides by reacting with hydrogen. They can form oxides which are either neutral or acidic.
