This model of Bohr’s idea of the atomic structure shows how it works. The nucleus lies in the center of the model and is made up of a certain number of protons and neutrons. Each of the outer layers is made up of a certain amount of electrons. The limit to how many electrons can be in each electron shell is shown in the model.

The modern model of the atom is based on quantum mechanics. The Bohr Model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all of the high-level math of the modern version. Bohr model of the atom was proposed by Neil Bohr in 1915.

Niels Bohr. Model of the Atom(Niels Bohr) In 1913 one of Rutherford'sstudents, NielsBohr, proposed a model for the hydrogen atom that was consistent with Rutherford's modeland yet also explained the spectrum of the hydrogen atom. The Bohr modelwas based on the following assumptions.
