The ratio of the speed of the electron in the first Bohr orbit of hydrogen and the speed of light is — Atomic Structure Chemistry Question
Question
The ratio of the speed of the electron in the first Bohr orbit of hydrogen and the speed of light is equal to (where e, h and c have their usual meanings)
Answer: D
💡 Solution & Explanation
The speed of an electron in the first Bohr orbit of hydrogen is $v = \frac{e^2}{2 \epsilon_0 h}$. The ratio $v/c = \frac{e^2}{2 \epsilon_0 hc}$. Therefore, correct answer is D.
