explanation of bhor`s atomic model?

Question

bhor`s atomic model is involed in finding the spectral lines of hydrogen like atoms

Answer 1

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.

Answer 4

Bhors atomic model consists of a nucleus containing protons and neutrons that has electrons 'orbiting' around it. Each electron (in the outermost shell) is capable of accepting or losing a 'quanta' of energy by changing its orbit. The exact magnitude of the quanta is determined by the 'binding force' exerted on the electron by the nucleus.

what's the relevance of you asking us how constrained is our self assurance in climate fashions? i myself don't understand your element in asking this question. this is how the technology works. fashions are in step with information attainable. while the fashions are ran they'll supply projected outcomes. people who have studied the technology then assign their degree of self assurance in as to how possibly those expected outcomes will grow to be. Examples: could the factors fashions anticipate that over the subsequent 50 years there will be a 300 foot sea point upward thrust, then people who have studied the technology could maximum frequently assign a low share element (<10%) that this can be the case. this could illustrate an extremely low degree of self assurance, by using the scientist, that this could particularly ensue. could the factors fashions anticipate that over the subsequent 50 years there will be a 3mm sea point upward thrust, then people who have studied the technology could maximum frequently assign a extreme share element (>ninety%) that this can be the case. this could illustrate an extremely extreme degree of self assurance, by using the scientist, that this could particularly ensue. Do the two of those variety runs tutor that for the period of 50 years there will be precisely a 300 foot sea point upward thrust or precisely a 3mm sea point upward thrust? NO! they only tutor opportunities and then the scientist could assign a level of self assurance in those opportunities. fashions do no longer anticipate absolutes. They never have and that they never will. fashions tutor opportunities based on the archives given. those opportunities could then be evaluated, by using somebody that particularly is familiar with what they're doing, and assigned a level of self assurance in those opportunities. the two you do no longer how fashions have been meant to paintings, you do no longer how scientist assign their degree of self assurance in variety predictions/projections or you intentionally attempt to create confusion here. it is it? i'm leaning in the direction of, "all the above"! are you able to narrow this down slightly from here?

Answer 6

according to bohr, an atom has electrons revolving around it in definite orbits and when energy is supplied to them, the electrons get 'excited' and move to a higher energy level. to become more stable, they try to return back to their ground state and in order to do so, they have to emit a photon of the same energy they have absorbed. as hydroges has only one electron, it emits a continuous spectra, ie. of the VIBGYOR series.

Answer 7

The concept of atom itself is flawed. Better to invent a different concept.
