The time of revolution of an electron around a nucleus of charge `Ze` in `n`th Bohr orbit is directly proportional to

The radii of Bohr's orbit are directly proportional to

The radii of Bohr's orbit are directly proportional to

Magnetic moment of an electron in n^("th") Bohr orbit is proportional to

Assertion: The de Broglie wavelength of an electron in n^(th) Bohr orbit of hydrogen is inversely proportional to the square of quantum number n. Reason: The magnitude of angular momentum of an electron in n^(th) Bohr orbit of hydrogen atom is directly proportional to n.

In Bohr's model of the hydrogen atom, let R, V, T and E represent the radius of the orbit, speed of the electron, time period of revolution of electron and the total energy of the electron respectively. The quantity proportional to the quantum number n is

Energy of an electron in n^(th) Bohr orbit is given as

Energy of an electron in n^(th) Bohr orbit is given as

According to Bohr's theory frequency of the revolution of electron in a Bohr's orbit is inversely proportional to
