In a mixture of H – He+ gas (He+ is singly ionized He atom), H atoms and He+ ions are excited to their respective first excited states. Subsequently, H atoms transfer their total excitation energy to He+ ions (by collisions). Assuming that the Bohr model of atom is applicable, answer the following questions.
The quantum number n of the state finally populated in He+ ions is :
- 2
- 3
- 4
- 5
Answer
(C) 4
