... When I went to write this problem I looked at the periodic table and saw that Rubidium had a mass of 85.467. Since the mass of all isotopes are even (or nearly so) and this average was uneven I knew immediately that rubidium had to have two major isotopes. When I looked up the isotopes sure enough t ...
