The ratio of the magnitude of the kinetic energy to the potential energy of an electron in the 5th excited state of a hydrogen atom is :
(3) 12
Bohr model: K= ke22r, U=- ke2r
|U|=2K for every orbit n (here n=6)
K|U|= 12
the ratio is the same for every orbit, n=6 (5th excited state) gives the same value.
Answer: (3)
An electron of hydrogen atom in an excited state is having energy En=-0.85 eV. The maximum number of allowed transitions to lower energy level is .
An electron revolving in nth Bohr orbit has magnetic moment n. If n nx, the value of x is
When a hydrogen atom going from n=2 to n=1 emits a photon, its recoil speed is x5 m/s. Where x= . (Use, mass of hydrogen atom =1.6 10-27 kg)
Given below are two statements: In the light of the above statements, choose the most appropriate from the options given below
Hydrogen atom is bombarded with electrons accelerated through a potential difference of V, which causes excitation of hydrogen atoms. If the experiment is being performed at T=0 K, the minimum potential difference needed to observe any Balmer series lines in the emission spectra will be 10 V, where = .
The radius of third stationary orbit of electron for Bohr's atom is R. The radius of fourth stationary orbit will be:
If Rydberg's constant is R, the longest wavelength of radiation in Paschen series will be 7R, where = .
