Among the following, the correct statement is
Options
- ATritium is radioactive and emits low energy -rays
- BH ⁺ does not exist freely
- CTritium is about one atom per 10^8 atoms of protium
- 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.
