WBCS.LIVE practice question

[ ⟶ + β+ + X ] in this nuclear reaction, what does X stands for?

Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. A neutron
  2. A neutrion
  3. A electrion
  4. A proton

Correct answer and explanation

Correct answer: A neutrion

Explanation: ✅ Correct Answer: B) A neutrion 📚 Explanation: In a nuclear beta-plus decay reaction where a proton converts into a neutron, a positron ($\beta^+$) is emitted along with an uncharged, nearly massless quantum particle known as a neutrino ($X$). This particle is essential to satisfy the laws of conservation of energy, momentum, and lepton number in nuclear interactions. It is a fundamental component of subatomic particle physics.
