Chapter 0, Problem 47RQ

Immediately after the big bang, helium and other very light elements up to about lithium were formed. It was not until stars were formed that heavier atoms up to iron were created. The heaviest naturally occurring elements did not form until the explosion of massive stars in supernovas. Look at the periodic table and divide it up by these masses. Is there any trend or information about these elements that you can determine from this information?
