bohr's model? how is it structured?

In atomic physics, the Bohr model depicts the atom as a small, positively charged nucleus surrounded by waves of electrons in orbit — similar in structure to the solar system, but with electrostatic forces providing attraction, rather than gravity, and with waves spread over entire orbit instead of localized planets.

Introduced by Niels Bohr in 1913, the model's key success was in explaining the Rydberg formula for the spectral emission lines of atomic hydrogen; while the Rydberg formula had been known experimentally, it did not gain a theoretical underpinning until the Bohr model was introduced.

The Bohr model is a primitive model of the hydrogen atom that cannot explain the fine structure of the hydrogen atom nor any of the heavier atoms. As a theory, it can be derived as a first-order approximation of the hydrogen atom in the broader and much more accurate quantum mechanics, and thus may be considered to be an obsolete scientific theory. However, because of its simplicity, the Bohr model is still commonly taught to introduce students to quantum mechanics. The link given below adequately describes the model - i hope I've been a help. Please chose me for best answer - as i need the points!!

Thanks

1st study the Rutherfoprd principle then follow Bohr's model.Just draw the spheres which r define as orbit and follow the octet rule ,or allow as much ele as in outermost noble gas configuration can have. dont puzzle ur self with the excited and ground state configuration of atoms
