When the radioactive nucleus astatine 215 decays, it tears the whole atom into two atoms, bismuth 211 and helium 4, 215 At - 211 Bi+ The masses of the three atoms are 215 15 At: 3.57019 x 10-25kg 211Bi: 3.50358 x 10-25kg • 4He: 6.647 x 10-27kg What is the kinetic energy released in the decay (in joules and in MeV)?
