Short Note

Write nuclear reaction equation for α-decay of `""_88^226"Ra"`.

Solution

α is a nucleus of helium `(""_2^4"He")` and β is an electron (e− for β and e+ for β+). In every α-decay, there is a loss of 2 protons and 4 neutrons. In every β+-decay, there is a loss of 1 proton and a neutrino is emitted from the nucleus. In every β-decay, there is a gain of 1 proton and an antineutrino is emitted from the nucleus.

For the given case, the various nuclear reaction can be written as:

`""_88^226"Ra" -> ""_86^222"Rn" + ""_2^4"He"`

  Is there an error in this question or solution?
