Bohr idea
In September 1911, Bohr, supported by a fellowship from the Carlsberg Foundation, travelled to England, where most of the theoretical work on the structure of atoms and molecules was being done. He met J. J. Thomson of the Cavendish Laboratory and Trinity College, Cambridge. He attended lectures on electromagnetism given by James Jeans and Joseph Larmor, and did some res… WebApr 6, 2024 · According to Bohr, electrons can revolve in a certain discrete (discontinuous) non-radiating orbits, called stationary (permitted) orbits, for which angular momentum (L) of the revolving electron is an integral multiple of. h 2 π. . Thus the angular momentum of the orbiting electron is an integer number. The angular momentum of an electron = mvr.

WebOct 17, 2024 · According to the Bohr model, higher energy orbits are located (closer to/further from) the atomic nucleus. This makes sense since negative electrons are (attracted to/repelled from) the positive protons in the nucleus, meaning it must take energy to move the electrons (away from/towards) the nucleus of the atom.

En = − (2.18 × 10 − 18)Z2 n2 J = − Z2 n2 Ry. Hence, the energy of the electron in an atom also is quantized. Equation 7.4.18 gives the energies of the electronic states of the hydrogen atom.
