Rb-87 isotope
WebSep 23, 2024 · So that the mass and atomic numbers have the same value on both sides, the mass number of the daughter isotope must be 12, and its atomic number must be 6. The element having an atomic number of 6 is carbon. Thus the complete nuclear equation is as follows: 12 5 B → 126 C +0 − 1e + γ. The daughter isotope is carbon-12. Web75 rows · Rubidium (37 Rb) has 36 isotopes, with naturally occurring rubidium being composed of just two isotopes; 85 Rb (72.2%) and the radioactive 87 Rb (27.8%).
