Choose the correct nuclear process from the below options [p: proton, n : neutron, e ⁻ : electron, e ⁺ : positron, v: neutrino, v : antineutrino]

Options

  1. An p + e ⁺+ v
  2. Bn p + e ⁺+ v
  3. Cn p + e ⁻+ v
  4. Dn p + e ⁻+ v

Correct answer

D. n p + e ⁻+ v

Step-by-step solution

For all nuclear processes, charge must be conserved. Also, when a release of an electron ( e⁻ ) is always accompanied by a release of an antineutrino ( v ) Hence, n p+ e ⁻+ v is the correct answer.
