Why do nonmetals not have their own name instead of being not like metals?

They do have their own names! The periodic table is actually split up into far more groups then just the metals and non-metals. The groups actually are as following: The Alkali metals The Alkaline earth metals The Lanthanides The Actinides The transition metals Other metals (all of the above are collectively grouped as the metals.) The Metaloids (these can neither be definitely grouped as metals or non-metals as they share properties of both.) Other non-metals The Halogens The Noble gases (these are collectively grouped as non-metals.) The reason for the fact that the collective groups being known as just the metals and non-metals is most likely due to the fact that there are far more metals, so it is more likely that these were discovered and then named first. There is no strong definition on what is a metal or non-metal, however, non-metals can generally be defined by having a negative valence whereas metals have a positive valence.
