    I am not so sure about whether Np or Fr is more rare in nature. Np is produced by neutron capture by Uranium. The neutrons stem from spontaneous fission of Uranium. With this hindsight, also the answer "90" in question 1 is more convention than fact.

    There is also a question of what is meant by 'nature' (per the question of how many elements exist in nature). 1) Smartass observatIon: People are part of nature.2) Wouldn't a supernova temporarily produce elements even beyond what people have created (possibly reaching a theorized island of [relative] stability)? Any any given moment (spatial hypersurface) in the universe, I would presume far more than 90 elements exist (without recourse to assumptions about intelligent aliens).
