An electron cannot revolve around the nucleus in a hydrogen atom at an arbitrary distance. Explain.
State Bohr's quantization condition for defining stationary orbits.
In accordance with the Bohr's model, find the quantum number that characterises the earth's revolution around the sun in an orbit of radius 1.5 × 1011 m with orbital speed 3 × 104 m/s. (Mass of earth = 6.0 × 1024 kg.)
The angular momentum of the electron in the nth allowed orbit is;
What is the angular momentum of an electron revolving in the 3rd orbit of an atom?
How much is the angular momentum of an electron when it is orbiting in the second Bohr orbit of hydrogen atom?
