Detailed explanation-1: -Bohr model, description of the structure of atoms, especially that of hydrogen, proposed (1913) by the Danish physicist Niels Bohr .
Detailed explanation-2: -In 1913, Neils Bohr, a student of Rutherford ‘s, developed a new model of the atom. He proposed that electrons are arranged in concentric circular orbits around the nucleus. This model is patterned on the solar system and is known as the planetary model.
Detailed explanation-3: -The theory notes that electrons in atoms travel around a central nucleus in circular orbits and can only orbit stably at a distinct set of distances from the nucleus in certain fixed circular orbits. Such orbits are related to certain energies and are also referred to as energy shells or energy levels.
Detailed explanation-4: -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-5: -According to the Bohr theory electrons revolves around the nucleus in circular orbit.
