Which of the following forms of hydrogen emits low energy β - particles?

Options

  1. ADeuterium H 1 2
  2. BProton H +
  3. CTritium H 1 3
  4. DProtium H 1 1

Correct answer

C. Tritium H 1 3

Step-by-step solution

Tritium isotope of hydrogen is radioactive and emits low energy β - particles. It is because of high n / p ratio of tritium which makes nucleus unstable. For tritium H 1 3 No. of neutron n = 2 No. of proton p = 1 n p = 2 ∵   n p is high tritium wil emit β particle.
