2. A hydrogen atom consists of a fixed nucleus with charge q = 1.6x10^-19 coulombs and mass M = 1.67x10^-27kg , around which a charge electron moves e=1.6x10^-19 coulombs and mass m = 9.1x10^-31 kg in a circular orbit of classical radius ao = 5.11x10^-11 m.

(a) Find the orbital velocity v of the electron and compare it with the velocity of light.

(b) Determine the total energy of the electron in this orbit in units of electron volts (eV), where 1 eV = 1.6x10^-19 joule.

Question 1 In this question we undertake the Hydrogen Atom Model, developed in 1913 by Niels Bohr. a) Write the electric force reigning between the proton and the electron, in the hydrogen atom, in CGS system. Then equate this force, with the force expressed in terms of mass and acceleration, to come up with Bohr's equation of motion. Suppose that the electron orbit, around the proton, is circular. Use the following symbols, throughout. e: proton's or electron's charge intensity(4.8x 10-8...

A hydrogen atom is made up of a proton of charge +Q = 1.60 x10-19 C and an electron of charge –Q= –1.60 x 10-19 C. The proton may be regarded as a point charge at the center of the atom. The motion of the electron causes its charge to be "smeared out" into a spherical distribution around the proton, so that the electron is equivalent to a charge per unit volume of ρ ( r ) = − Q...
