According to Bohr's model of hydrogen atom, which of the following statement is incorrect?
- A Radius of \(3^{\text {rd }}\) orbit is nine times larger than that of \(1^{\text {st }}\) orbit.
- B Radius of \(8^{\text {th }}\) orbit is four times larger than that of \(4^{\text {th }}\) orbit.
- C Radius of \(6^{\text {th }}\) orbit is three time larger than that of \(4^{\text {th }}\) orbit.
- D Radius of \(4^{\text {th }}\) orbit is four times larger than that of \(2^{\text {nd }}\) orbit.
Answer & Solution
Correct Answer
(C) Radius of \(6^{\text {th }}\) orbit is three time larger than that of \(4^{\text {th }}\) orbit.
