Question:

Match List I with List II using Bohr's atomic model:

LIST I	LIST II
A. Radius of electron orbit	I. directly proportional to '$n^2$'
B. Angular momentum of electron	II. directly proportional to 'n'
C. Velocity of electron	III. Inversely proportional to 'n'
D. Energy of electron	IV. inversely proportional to '$n^2$'

Choose the correct answer from the options given below:

Options:

A-I, B-II, C-III, D-IV

A-II, B-I, C-III, D-IV

A-I, B-II, C-IV, D-III

A-IV, B-III, C-II, D-I

Correct Answer:

A-I, B-II, C-III, D-IV

Explanation:

The correct answer is Option (1) → A-I, B-II, C-III, D-IV

LIST I	LIST II
A. Radius of electron orbit	I. directly proportional to '$n^2$' [$r_n=n^2.a_0$]
B. Angular momentum of electron	II. directly proportional to 'n' $[L=\frac{nh}{r}]$
C. Velocity of electron	III. Inversely proportional to 'n' $[V_n=\frac{e^2}{2ε_0h}\frac{1}{n}]$
D. Energy of electron	IV. inversely proportional to '$n^2$' $[E=\frac{13.6}{n^2}eV]$
