What led to the discovery of the bohr model?
Neils Bohr discovered it one day
Niels Bohr predicted that the electrons would be found orbiting the nucleus in energy levels that could be compared to what?
Niels Bohr predicted that the electrons would be found orbiting the nucleus in specific energy levels that could be compared to the rungs of a ladder. He proposed that electrons can only exist in these discrete energy levels and that they move between levels by absorbing or emitting specific amounts of energy. This led to the development of the Bohr model of the atom.
How many shells are in a Bohr atomic model?
Bohr model consists only one shell.(a hydrogen atom shell) But shell can be increased by exciting the atom. When the electron comes to its shell it loses energy,therefore,different types of regions have been observed i.e,(Lyman,Balmer,Paschen,Bracket and Pfund)
Which experimental discovery led Niels Bohr to revise Rutherford's model of the atom?
Jj Thompson in 1904.................. Actually it was Ernest Rutherford who Disproved it in 1911. JJ thompson was the creator of the plum pudding theory
How many different atomic numbers are there?
By atomic models I assume you mean how we say an atom works and is arranged. There have been three major atomic models in history: The plum-pudding model said that negatively-charged particles (the precursor to electrons) were suspended in a positively-charged "soup" (the plum pudding). Rutheford disproved this model with his experiments, which led to Niels Bohr inventing the Bohr model of the atom, which has electrons orbiting the nucleus in predefined orbits (called "orbitals"). Although we know that the Bohr model is incorrect, it is very close to the correct (quantum-mechanical) model, so that's what is taught in most elementary and high schools. Nowadays, only the third model is considered correct: the quantum mechanical model. It is based on Max Planck's quantum theory and involves electrons flying around in three-dimensional clouds (also called "orbitals"). The QM model is pretty complex but it's rather simple compared to string theory and other physics concepts.
What led niels bohr to his discover?
Bohr proposed his model for the atom because (1) it easily explained spectral lines of hydrogen and (2) other models failed to do so. The model was accepted when it was successful in predicted spectral lines of ionized helium.

One of the discoveries that led to the modern view of the Solar System was that the BLANK of the planets were ellipses?
One of the discoveries that led to the modern view of the Solar System was that the "orbits" of the planets were ellipses.
Who was the first scientist to dispute ptolemy model of geocentric of earth center universe?
The first astronomer to dispute the model seriously was Nicholas Copernicus in the 1500s. His model used circles and epicycles, like the old Ptolemaic model, but had the Sun at the centre, which led to its being named the heliocentric model. Sixty years after his death in 1543, the Copernicus model was taken up by Galielo in his dispute with the Catholic church. In the latter half of the 1600s further discoveries led to wider acceptance of the heliocentric concept. However the rest of the Copernicus model was discarded and replaced by Kepler's model which had each planet in an elliptical orbit, and this was taken up and given scientific credibility by the discoveries of Newton and others.

Who came up with the electron cloud model of the atom?
In 1926, austrian physicist erwin schrodinger wondered why electrons had to be limited to specific orbitals as proposed by neils bohr. He proposed a new model in which electron move in cloudlike orbits rather than fixed ones. He said it is impossible to know the exact location of electrons. The best we can do is know where the electron probably is. Physicists still use the quantum model of the atom today.
How did gregor Mendel affect agriculture?
The impact of Gregor Mendel's discoveries impacted the world by reducing famine in the world. His discoveries also led to the scientific community having a better understanding of evolution.
