Answer: The mass number of daughter isotope (Radon) is 210 u

Step-by-step explanation:

Alpha decay is defined as the decay process in which alpha particle is released. In this process, a heavier nuclei decays into a lighter nuclei. The alpha particle released carries a charge of +2 units and a mass of 4 units.

In this decay process, the atomic number of the atom decreases by 2 units and the mass number decreases by 4 units.

The chemical equation for alpha decay of Radium-214 isotope follows


_(88)^(214)\textrm{Ra}\rightarrow _(86)^(210)\textrm{Rn}+_2^4\alpha

The daughter isotope formed is Radon-210. The mass number of formed isotope is 210 u

Hence, the mass number of daughter isotope (Radon) is 210 u
