Chemistry-Bohr's Model
NEET Chemistry Bohr's Model MCQ Question
Type: MCQ-numerical-Hard-Class 11
Calculate the energy difference in joules between the n=1 and n=5 orbits in a hydrogen atom using Bohr's model. The energy of the first orbit is given as -2.18 × 10^-18 J atom^-1.
A
2.09 × 10^-18 J
B
1.94 × 10^-18 J
C
2.04 × 10^-18 J
D
1.75 × 10^-18 J
Correct Answer
Option A
Detailed Explanation
Using the formula E_n = -2.18 × 10^-18 J / n^2, calculate E_5 and find the energy difference: E_1 - E_5 = 2.09 × 10^-18 J.
