Well, here is the estimate of the range limit on what can be defined as a chemical, 23.5 tons give or take some several hundred pounds( or there about ). Count all the atoms in the 23.5 tons of a pure substance and that is the largest chemical of a pure substance, change one atom and you have another chemical. how many times you can change it around tells you how many chemicals there are. why 23.5 tons, because around 23.5 tons,atoms do not hold togeather, it is a natural fracture in atomic grouping of atoms, at which if you add another atom to the 23.5 tons some other atom will leave the group and be added to another group that is close to 23.5 tons. you might call it a chemical threshold for another name. I hope that help simplify the issue, because otherwise you will become very confused. Dwayne D.L.Rabon
Readers, this would appear to have been written from the confines of a mental institution, somewhere in the USA (judging by the use of non-metric units). You can safely ignore everything in it.
Along with each and every other post made by Rabon. Not once has he made a rational (or even supported) claim. He doesn't do science. He doesn't know what science is.
