The Geocentric model of the solar system proposed that the Earth was at the centre of the system (and universe), while the sun and planets revolved around the Earth. We now know this not to be true and that the sun is at the centre of the solar system (Heliocentric).

∙ 13y agoNiels Bohr proposed a simplistic model of the hydrogen atom that he thought was similar to the Sun with a single planet. Later research into quantum mechanics has revealed that even at its simplest, there really is no resemblance between them.

∙ 12y agothe planatery system for arranging atoms is proposed by rutherford after his famous alpha ray scattering experiment,he passed alpha rays through a small gold foil of ignorable thickness and covered it with detecting screen,he found the nucleus by this experiment,also he proposed electrons are revolving at very high speeds around the nucleus,but this model failed to explain stability of atoms according to maxwells law which says a rotating charged particle will emit energy,according to it the electron will fall to nucleus,so its failed!

What areas did Niels Bohr make contributions in?
He made a model of the atom, with electrons circling the nucleus.
What was Niels Bohr contribution to the atom?
The Bohr model of the atom, the theory that electrons travel in discrete orbits around the atom's nucleus.The shell model of the atom, where the chemical properties of an element are determined by the electrons in the outermost orbit.The liquid drop model of the atomic nucleus.Identified the isotope of uranium that was responsible for slow-neutron fissionThis answers came from wikipedia
Who came up with the 4-part atomic theory in 1805?
The first person to develop the first model of the atom in 1803 was John Dalton.
Why is the quantum theory important to the history of the atom?
it became the basis for all chemistry from then on
Who was the scientist responsible for the wave mechanics or quantum mechanics model of the atom was?
During the 1920s Austrian physicist Erwin Schrödinger (1887-1961) introduced what came to be known as the wave mechanical model, also known as the particle-wave hypothesis.
Who came up with the proton model of the atom?
John Dalton
What areas did Niels Bohr make contributions in?
He made a model of the atom, with electrons circling the nucleus.
Which scientist came up with the Electron cloud model of the atom?
Bohr-Rutherford

Where does atom came from?
atom is from Spain
Who created the first model of a atom?
The Australian scientist, M Vella came up with this model in the late 1900's.

Which scientist or scientists came up with the Electron Cloud nodel of the atom?
I think you're referring to JJ Thomson's model. It is more oftenly called the 'plum-pudding model'.
Descibe Thomson atomic model?
J.J. Thompson was the person who suggested the plum pudding model for the atomic structure. He declared that the electrons are located between a cloud of the positive charges. This model was proven incorrect from the alpha particle experiment done by Ernest Rutherford.
How did Bohr improve Planck's theoory?
Bohr came up with the planetary model for the hydrogen atom - that began the physical explanation of quantum mechanics invented by Planck.
18 The model of the atom proposed by Greek philosophers appears similar to the model proposed centuries later by Dalton What was the key difference between the two models?
The Greeks knew you could split an atom via nuclear fission, and used philospohy and logic. Dalton used experimental plates to check for a nucleus and came up with his model experimentally.
Who came up with the 4-part atomic theory in 1805?
The first person to develop the first model of the atom in 1803 was John Dalton.
