Bohr atomic theory definition
Nevertheless, Bohrs model remains useful as an instructional tool for introducing students to more modern theories such as quantum mechanics and the valence shell atomic model.Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. Although the Bohr model has been supplanted by other models, its underlying principles remain valid. bohr atomic theory definition
The Bohr model works well for very simple atoms such as hydrogen (which has 1 electron) but not for more complex atoms. Although the Bohr model is still used today, especially in elementary textbooks, a more sophisticated (and complex) model the quantum mechanical model

Atomic Structure and Bohr Model. 1. Describe the evolution of atomic theory leading to the current model of the atom based on the works of Democritus, Dalton, Thomson, Rutherford, Bohr, and Schrodinger. 2. Explain the law of conservation of mass, the law of definite proportions, and the law of multiple proportions.
Two models of atomic structure are in use today: the Bohr model and the quantum mechanical model. The quantum mechanical model is based on mathematics. Although it is more difficult to understand than the Bohr model, it can be used to explain observations made on complex atoms.

Bohr theory definition, a theory of atomic structure in which the hydrogen atom (Bohr atom) is assumed to consist of a proton as nucleus, with a single electron moving in distinct circular orbits around it, each orbit corresponding to a specific quantized energy state: the theory was extended to other atoms.
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. The motion of the electrons in the Rutherford model was unstable because, according to classical mechanics and electromagnetic theory, any charged particle moving on a curved path emits
Bohr atomic model, description of the structure of atoms, especially that of hydrogen, proposed (1913) by the Danish physicist Niels Bohr. The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantummechanical models.
Bohr theory n. An early model of atomic structure in which electrons travel around the nucleus in a number of discrete stable orbits determined by quantum conditions.
