Radium-226 decays with a half-life of 1,620 years to radon-222 plus a helium nucleus ( (alpha) particle)

Question:

Radium-226 decays with a half-life of 1,620 years to radon-222 plus a helium nucleus ( $\alpha$ particle) according to the nuclear reaction equation

\[{ }_{88}^{226} \mathrm{Ra} ightarrow{ }_{86}^{222} \mathrm{Rn}+{ }_{2}^{4} \mathrm{He} .\]

The atomic masses are
