Isotopes of rubidium

Rubidium (37Rb) has 35 known isotopes, from 72Rb to 106Rb, with naturally occurring rubidium composed of two: stable 85Rb (72.2%) and radioactive 87Rb (27.8%). The primordial radionuclide 87Rb has a half-life of 4.97×1010 years, beta decaying to stable 87Sr. It is, as the element is, widespread on Earth as rubidium readily substitutes for potassium in…
