      Not very much. Some suggest less than 30 grams! Moreover, Francium is the most unstable of all naturally occurring elements – its atoms fall apart (its half-life) in 22 minutes!
      What is great about Francium (apart from its name – it was discovered in France!) is that scientists predicted it existed before anyone found it!
