Problem: The following nuclei are observed to decay by emitting an α particle: 212/84Po Part AWrite out the decay process for 212/84Po.Part BDetermine the energy released in this reaction. Be sure to take into account the mass of the electrons associated with the neutral atoms.

FREE Expert Solution

For an α-decay, the mass number of the nucleus is always reduced by 4 and the charge number reduced by 2 for the given nucleus.

The energy released in the reaction:

E=(m)(931.5MeV)

Part A

For an α - decay, we have the decay process for 212/84Po as:

 84Po2122He4 + 82Pb208 + ΔE
