GENERAL KNOWLEDGE

Detailed explanation-1: -The Bohr’s model of atom is familiarly recognized as planetary model. This model was proposed by Neils Bohr in which he overcame various drawbacks of Rutherford’s model. Thus the planetary model of atom was proposed by Neils Bohr.

Detailed explanation-2: -In July of 1913, Danish physicist Niels Bohr published the first of a series of three papers introducing this model of the atom, which became known simply as the Bohr atom.

Detailed explanation-3: -According to the Bohr model, often referred to as a planetary model, the electrons encircle the nucleus of the atom in specific allowable paths called orbits. When the electron is in one of these orbits, its energy is fixed.

Detailed explanation-4: -In Rutherford’s model of the atom, which is shown in the Figure below, the electrons move around the massive nucleus like planets orbiting the sun. That’s why his model is called the planetary model. Rutherford didn’t know exactly where or how electrons orbit the nucleus.

Detailed explanation-5: -Bohr Atomic Model : In 1913 Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus.
