In Exercise. 11 obtain the frequency of revolution of the electron in tis circular orbit. Does the answer depend on the speed of the electron ? Explain .

Text Solution

Verified by Experts

Frequency in Exercise 11. `upsilon = (qB)/(2pim) = (1.6 xx 10^(-19)xx6.5 xx 10^(-4))/(2 xx pi xx 9.1 xx 10^(-31))=18 MHz`

A lithium atom has three electrons. Assume the following simple picture of the atom Two electron moves close to the nucleus making up a spherical cloud it and the third moves outside the cloud in a circular orbit . Bohr's model can be used for the motion of this third electron but n = 1 state are not available to it. Calculate the ionization energy of lithium in ground state using the above picture.

In the Bohr model of a hydrogen atom, the centripetal force is furnished by the coulomb attraction between the proton and the electron. If a_0 , is the radius of the ground state orbit, m is the mass, e is the charge on the electron and epsilon_0 is the vacuum permittivity, the speed of the electron is

In the Bohr model of hydrogen atom, the electron is treated as a particle going in a circle with the centre at the proton. The proton itself is assumed to be fixed in an inertial frame. The centripetal force is provided by the Coloumb attraction. In the ground state, the electron goes round the proton in a circle of radius 5.3xx10^-11m . Find the speed of the electron in the ground state. Mass of the electron =9.1xx10^-31 kg and charge of the electron = 1.6xx10^-19C .
