Non-Metals
A non-metal is an element that is neither malleable nor ductile, and does not conduct electricity.Some of the examples of non-metals are : Carbon, Sulphur, Phosphorus Hydrogen, Fluorine, Chlorine, Bromine, Iodine, Helium, Neon, Argon, Krypton, and Xenon. Diamond and Graphite are also non-metals. They are the allotropic forms of carbon. All the non-metals are solids or gases, except bromine which is a liquid non-metal at room temperature.
