उत्तर

`v  α  1/n`

`v_1/v_3 = n_3/n_1`

`V_0/v_3 = 3/1 (Here  v_1 = V_0)`

`v_3 = V_0/3`

The velocity of an electron in the 3rd orbit of a hydrogen atom is `1/3` of the velocity of an electron in the 1st orbit.

State Bohr’s postulate of hydrogen atom which successfully explains the emission lines in the spectrum of hydrogen atom. Use Rydberg formula to determine the wavelength of Hα line. [Given: Rydberg constant R = 1.03 × 107 m−1]


What is the maximum number of emission lines when the excited electron of an H atom in n = 6 drops to the ground state?


The gravitational attraction between electron and proton in a hydrogen atom is weaker than the Coulomb attraction by a factor of about 10−40. An alternative way of looking at this fact is to estimate the radius of the first Bohr orbit of a hydrogen atom if the electron and proton were bound by gravitational attraction. You will find the answer interesting.
