Choose the correct nuclear process from the below options [p: proton, n: neutron, e⁻: electron, e⁺: positron, ν: neutrino, ν̄: antineutrino] (1) n → p + e⁺ + ν̄ (2) n → p + e⁻ + ν (3) n → p + e⁺ + ν̄ (4) n → p + e⁻ + ν̄

  1. n → p + e⁺ + ν̄
  2. n → p + e⁻ + ν
  3. n → p + e⁺ + ν̄
  4. n → p + e⁻ + ν̄

Correct answer: n → p + e⁺ + ν̄

Solution

The correct option describes the process of beta-plus decay, where a neutron decays into a proton, emitting a positron and an antineutrino. This process conserves charge and lepton number, making it a valid representation of nuclear decay.
