Development of is process was aided by German chemist Fritz Strassmann, who later went on to discover nuclear fission wi German chemist Otto Hahn. 31,  · For example, strontium-86 has 38 protons and 48 neutrons, whereas strontium-87 has 38 protons and 49 neutrons. Radioactive elements, such as rubidium-87 (but not strontium-86 or strontium-87. In e rubidium-strontium me od, rubidium-87 ays wi a half-life o 8.8 billion years to strontium 87. Strontium has several o er isotopes at are stable and do not ay. e ratio of strontium-87 to ano er stable isotope, say strontium-86, increases over time as more rubidium-87 turns to strontium-87. In rubidium-strontium dating, e ratio of rubidium-87 to its stable product strontium-87 gives ages to several ousand million years. In carbon dating, e proportion of carbon-14 (half-life 5730 years) to stable carbon-12 absorbed into once-living matter gives ages to several ousand years. 01, 1996 · Rubidium has a larger atomic size an strontium, so rubidium does not fit into e crystal structure of some minerals as well as o ers.
