Nonmetal
They gain electrons when reacting with a metal. They are generally not lustrous and are bad conductors of heat and electricity. Some are gases including: hydrogen, helium, oxygen, nitrogen, fluorine, neon or radon and others.  An example of a solid that is a nonmetal is sulfur. It is yellow and not shiny at all. An example of a liquid that is a nonmetal is bromine. It is red. A non-metal is a good insulator for heat and cold. Usually, gases or brittle solids are non-metals.
