Question

Which one of the following emissions takes place in the nuclear reaction?

 90Th234 → 91Pa232 + ______ + 20n1

Options
  • A

    Alpha

  • B

    Gamma 

  • C

    Beta 

  • D

    Photons 

Explanation

Since the atomic mass is reduced by 2 and the atomic number is reduced by 1, beta emission has taken place along with emission of two neutrons since beta particles have atomic mass and atomic number of 0 and 1 respectively.
