Answer: The mass number of daughter isotope (Radon) is 210 u
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
[tex]_{88}^{214}\textrm{Ra}\rightarrow _{86}^{210}\textrm{Rn}+_2^4\alpha[/tex]
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
