Among the following, the correct statement is

Options

  1. ATritium is radioactive and emits low energy -rays
  2. BH ⁺ does not exist freely
  3. CTritium is about one atom per 10^8 atoms of protium
  4. DHydrogen is very reactive compared to halogen

Correct answer

B. H ⁺ does not exist freely

Step-by-step solution

Tritium is radioactive and emits low-energy beta-particles. H ⁺ does not exist freely but as H ₃ O ⁺ ion. Tritium is about 1 atom per 10¹⁸ atoms of protium. Hydrogen is less reactive than halogen which are good oxidizing agents. Thus, (b) is correct.
