Minimum excitation potential of Bohr's first orbit of Hydrogen atom is_____.
Options
- A3 . 6   V
- B10 . 2   V
- C13 . 6   V
- D3 . 4   V
Correct answer
B. 10 . 2   V
Step-by-step solution
Minimum excitation energy of Bohr's first orbit of Hydrogen atom is given by, ∆ U = 13 . 6 1 - 1 2 2   eV ⇒ ∆ U = 10 . 2   eV So minimum excitation potential of Bohr's first orbit of Hydrogen atom is 10 . 2   V
