An electron revolving in nth Bohr orbit has magnetic moment n. If n nx, the value of x is
(4) 1
The revolving electron behaves as a current loop: i = eT = ev2 r
so its magnetic moment is = iA = ev2 r r2 = evr2
In Bohr's model rn n2 and vn 1n
hence n vnrn 1n n2 = n, which means x = 1
Answer: (4)
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 = .
