Be careful with this: most schools define the use of other's ideas as your own as plagarism. Just make sure to cite the person.

Thanks... My book is "World of Chemistry", 2002 I think. I'm a hs sophomore, so perhaps it's not that accurate.

Hi, I was wondering if anyone could help me out here. My chem book says that there are 88 naturally occuring elements... but other places say 90, or 92, or 83! Does anyone know what the 88 are and how they distinguish "naturally occuring" ? Thanks!
