Question

Radon- 222 $\left(\frac{222}{86} \mathrm{Rn}\right)$ is released into the air during uranium mining and undergoes alpha decay to form ${ }_{84}^{218} \mathrm{Po}$ of mass 218.0090 u. Determine the energy released by the decay reaction. Most of this energy is in the form of alpha particle kinetic energy.

Step 1

First, we need to find the mass of the alpha particle, which consists of 2 protons and 2 neutrons. The mass of a proton is approximately 1.0073 u, and the mass of a neutron is approximately 1.0087 u. So the mass of an alpha particle is: $M_\alpha = 2 \times Show more…
