In an atom electrons revolve around the nucleus along a path of radius 0.72 A making 9.4 x 1014 revolutions per second. The equivalent current is. (Given e = 1.6 x 10-19 C)
Binding energy of Nitrogen Molecule 147N . Given m (147N) = 14.00307 a.m.u
An electron is revolving in its Bohr orbit having Bohr radius of 0.529 Å, then the radius of third orbit is
In accordance with the bohr's model the quantum number that characterises the earth revolution around the sun in an orbit of radius 1.5 x 1011 m with orbital speed 3 x 104 m/s is [given mass of the earth = 6 x 1024 kg]
The radius of hydrogen atom in the ground state is 0.53 Å .After collision with an electron it is found to have a radius of 2.1 Å, the principal quantum number 'n' of the state of the atom is
