Question

Radon is obtained from Radium due to

Answer 1

Radioactivity of Radium:

• Radon ($\mathrm{Rn}$) is a radioactive noble element that is formed by the transmutation of the Radium atom.
• Radium atomic nucleus decays by emitting alpha particles and gets converted into Radon nucleus.
• $\underset{\mathrm{Radium}}{{}_{88}{}^{226}\mathrm{Ra}}\to -\underset{\mathrm{Radon}}{{}_{86}{}^{222}\mathrm{Rn}}+\underset{\mathrm{alpha}\mathrm{particle}}{{}_2{}^4\mathrm{\alpha }}$
• In this reaction of the radioactivity of Radium, the Radium atom emits two alpha particles (that are the nucleus of helium) and gets converted to Radon.
