Velocity of an electron in nth orbit

Derive an expression for the velocity of an electron revolving round the nucleus in the orbit of hydrogen atom. From Bohr postulate, the centripetal force is provided by the electrostatic force between the nucleus and the electron, i. Byju's Answer. Open in App. By assuming Bohr's postulates derive an expression for radius of n t h orbit of electron, revolving round the nucleus of hydrogen atom. Derive an expression for critical velocity of a satellite revolving around the earth in a circular orbit. On the basis of Bohr's postulates derive an expression for orbital velocity of an electron in n th stationary orbit of hydrogen atom. What will be the kinetic energy of the electron in this state? An electron in the ground state of hydrogen atom is revolving in anticlockwise direction in a circular orbit of radius R. Obtain an expression for the orbital magnetic moment of the electron. The frequency of an electron is n when it is revolving around nucleus of hydrogen atom in 1 s t orbit. The frequency of same electron when it is revolving in 2 n d orbit is. Matter Waves. Standard XII Physics.

Bohr's model of hydrogen is based on the nonclassical assumption that electrons travel in specific shells , or orbits, around the nucleus. Bohr explained the hydrogen spectrum in terms of electrons absorbing and emitting photons to change energy levels, where the photon energy is. Bohr's model does not work for systems with more than one electron. The planetary model of the atom.

Velocity of an electron in nth orbit

Hey there! We receieved your request. Various other concepts like radiation less orbits and stationary states were also introduced in the Bohr Model. We discuss the postulates of Bohr Atomic theory. Bohr introduced the concept of radiation less orbits in which the electrons revolve as usual around the nucleus but without radiating any kind of energy which is contrary to the laws of electromagnetism. This was a hypothesis, but at least a working one. Radiation occurred only when an electron made a transition from one stationary state to another.

The following is the relation between the object distance and the image distance in a plane mirror image :. Please add your first playlist.

Bohr's model of the atom was valuable in demonstrating how electrons were capable of absorbing and releasing energy, and how atomic emission spectra were created. However, the model did not really explain why electrons should exist only in fixed circular orbits, rather than being able to exist in a limitless number of orbits with different energies. In order to explain why atomic energy states are quantized, scientists had to rethink their views of the nature of the electron and its movement.
