The main characteristic is it is not a metal, so it doesn't conduct electricity, isn't shiny, and doesn't form cations.
The non metals are at the right hand side of the Periodic Table and include group 17 along with C, N, P, O, and S. The other elements in group 14, 15 and 16 are the metalloids, which are have intermediate properties.
The density is a physical characteristic of all materials.
The characteristic of non-metals are-1. Non-metals are gases or solids at room temperature, except bromine, which is liquid at room temperature.2. Non-metal solids are generally not as hard as metals and have low tensile strengths. However diamond, an allotrope of carbon, is very hard.3. They do not have luster. However, silicon, iodine and graphite have metallic lustre.
Neon is a non-metal. It is one of the Noble Gasses which are all non-metals.
