Match the following List-I with List-II in connection with Bohr's atomic model.
Options
- Ai iii ii iv
- Bii iv iii i
- Ciii i iv ii
- Diii i ii iv
Correct answer
A. i iii ii iv
Step-by-step solution
A) Speed of revolution of electron, = 1 4 ₀ 2 Z e^2 n h (B) Kinetic energy = ( 1 4 ₀ )^2 2 ^2 m e^4 Z^2 n^2 h^2 (C) Total Energy =- ( 1 4 ₀ )^2 2 ^2 m e^4 Z^2 n^2 h^2 (D) Frequency = ( 1 4 ₀ )^2 4 ^2 Z^2 e^4 m n^3 h^3 Hence, A i ; B iii ; ii; D iv.
