When a neutron is disintegrated to give a -particle,

Options

  1. Aa neutrino alone is emitted
  2. Ba proton and neutrino are emitted
  3. Ca proton alone is emitted
  4. Da proton and an antineutrino are emitted

Correct answer

D. a proton and an antineutrino are emitted

Step-by-step solution

A beta minus particle ( ⁻ ) is an electron. Emission of ⁻ involves transformation of a neutron into a proton, an electron and a third particle called antineutrino ( v ) . ₀ n ¹= ₁ p ¹+ _ -1 ⁰+ v
