The elements generally regarded as nonmetals are: * hydrogen (H) * In Group 14: carbon (C) * In Group 15(the pnictogens): nitrogen (N), phosphorus (P) * Several elements in Group 16, the chalcogens: oxygen (O), sulphur (S), selenium (Se) * All elements in Group 17 - the halogens * All elements in Group 18 - the noble gases Common properties considered characteristic of a nonmetal include: * poor conductors of heat and electricity when compared to metals * they form acidic oxides (whereas metals generally form basic oxides) * in solid form, they are dull and brittle, rather than metals which are lustrous, ductile or malleable * usually have lower densities than metals * they have significantly lower melting points and boiling points than metals * non-metals have high electronegativity

They are in between the metals and non metals
Are most of the element metals or non metals?
Non metals

non metals
What are the metals and non metals in your body?
all are non metals
Are tent poles made out of non metals or metals?
non metals
Which are better metals or non metals?
My opinion would be metal. Since non metals are brittle and dull, I disagree with the non-metals.
Where are the most reactive non metals?
The most reactive non metals are Halogens which may combine most of the metals as well as non metals.
Are inert gases such as helium and neon classified as metals or non-metals?
Non-metals
Are non metals semiconductors?
Metals are conductors. Semiconductors are usually non-metals or metalloids.
