Are there really only, ’92 naturally occurring elements’?

March 11, 2012

This question recently came up on the AP Chemistry listserv, and rather than answering it there (where I like to keep things strictly AP Chem if I can), I thought I would give the answer that I gave when I researched my book, “How To Make A Universe With 92 Ingredients‘, here instead.

The answer is ‘yes and no’, and it depends on how you count them. The relevant piece from the book is pictured below.

92?
