Sagot :

The result of two alpha decay of Thorium 230 is Radon-222.

What is alpha decay?

The radioactive decay results in the release of the subatomic particles resulting in reduction in the mass number by 4, and the atomic number by 2.

The result of alpha decay of thorium 230 is given as:

  • First decay:

[tex]\rm ^{230}_{90}Th\;\rightarrow\;^{226}_{88}Ra\;+\;^{4}_{2}\alpha[/tex]

  • Second decay:

[tex]\rm ^{226}_{88}Ra\;\rightarrow\;^{222}_{86}Rn\;+\;^{4}_{2}\alpha[/tex]

The result of two alpha decay of Thorium 230 is Radon-222.
