The Bohr model, developed in 1913, explained how electrons have stable orbits around the nucleus. The model was proposed by Niels Bohr. The Bohr model shows the atom as a tiny, positively-charged center, surrounded by electrons. These electrons travel in small circular orbits around the nucleus. The attraction of the electrons was electrostatic forces.

Niels Bohr (1885 – 1962) The model introduced the theory of electrons traveling in orbits around the atom’s nucleus, the chemical properties of the element being largely determined by the number of electrons in the outer orbits. Bohr also introduced the idea that an electron could drop from a higher-energy orbit to a lower one,

Niels Bohr Niels Bohr proposed the first model of the atom with distinct energy levels with quantized energies. He proposed this theory based on the spectra of atoms and ions.

Every atom tested unexpectedly exhibited discrete spectral lines instead of the expected continuous spectrum. It was if atoms were able to absorb and emit energy only of certain discrete frequencies.

The Bohr model of atomic structure was developed by Danish physicist and Nobel laureate Niels Bohr (1885 – 1962). Published in 1913, Bohr’s model improved the classical atomic models of physicists J. J. Thomson and Ernest Rutherford by incorporating quantum theory.
