Niels Bohr Atomic Model (also The Planetary Model):


Niels Bohr envisioned the atom with electrons circling the nucleus of an atom in rings. Though Bohr’s Satellite model failed it is by far the most successful model, so far. That is, until “THE GENERAL FIELD TREORY OF PHYSICS”.



Content regarding the Biels Bohr Atom: In 1922, Nobel prize winner Niels Bohr revised Rutherford’s model by suggesting that

  • The electrons were confined into clearly defined orbits.
  • They could jump between these orbits, but could not freely spiral inward or outward in intermediate states.
  • An electron must absorb or emit specific amounts of energy for transition between these fixed orbits
