Bohr model

model introduced bi Niels Bohr an Ernest Rutherford in 1913

In atomic pheesics, the Rutherford–Bohr model or Bohr model or Bohr diagram, introduced bi Niels Bohr an Ernest Rutherford in 1913, depicts the atom as a smaw, positively chairged nucleus surroondit bi electrons that traivel in circular orbits aroond the nucleus—similar in structur tae the Solar Seestem, but wi attraction providit bi electrostatic forces rather nor gravity.

The Rutherford–Bohr model o the hydrogen atom (Z = 1) or a hydrogen-lik ion (Z > 1), whaur the negatively chairged electron confined tae an atomic shell encircles a small, positively chairged atomic nucleus an whaur an electron jimps atween orbits it is accompanied bi an emittit or absorbed amoont o electromagnetic energy ().[1] The orbits in which the electron can traivel are shawn as grey circles; thair radius increases as n2, whaur n is the principal quantum nummer. The 3 → 2 transeetion depicted here produces the first line o the Balmer series, an for hydrogen (Z = 1) it results in a photon o wavelenth 656 nm (reid licht).
