Explanation / Answer

83 Bi 209 + 2 He4 ------> 85 At 211 + 20 n 1 The sum of the atomic numbers on the reactants side = sum ofthe atomic numbers on the products side Simillarly The sum of the mass numbers on the reactants side =sum of the mass numbers on the products side So the required particle is alpha particle. The sum of the mass numbers on the reactants side =sum of the mass numbers on the products side So the required particle is alpha particle.
