the 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 else can I help you with?
What areas did Niels Bohr make contributions in?
He made a model of the atom, with electrons circling the nucleus.
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.
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
Why is the quantum theory important to the history of the atom?
it became the basis for all chemistry from then on
Which came first the theory of natural selection or the theory of relativity or the heliocentric theory or the theory of the the hydrogen atom?
In the following order: Heliocentric theory of the solar system (Aristarchus of Samos, 270 BCE) Natural Selection (Darwinian evolution, 1858) Theory of the hydrogen atom (as a small negatively charged particle inside a larger positively charged particle, 1904, the plum pudding model) Theory of relativity (special relativity, 1905) Theory of relativity (general relativity's initial paper on the acceleration of objects within the framework of special relativity, 1907) Theory of the hydrogen atom (as a small particle orbiting the atomic nucleus, 1909, the Rutherford or Planetary model) Theory of the hydrogen atom (as an "electron cloud" surrounding the atomic nucleus, 1913, the quantum mechanical or Bohr model) Theory of relativity (general relativity and its ability to warp space-time, 1915) So heliocentrism was, by about two millenia, the first. Relativity and the model of the hydrogen atom are intricately intertwined, so which came first depends on what you mean specifically.
Who came up with the proton model of the atom?
John Dalton
Which scientist came up with the Electron cloud model of the atom?
Bohr-Rutherford
What areas did Niels Bohr make contributions in?
He made a model of the atom, with electrons circling the nucleus.
Where does atom came from?
atom is from Spain
What was Niels Bohrs contribute to atoms?

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

The first person to develop the first model of the atom in 1803 was John Dalton.

What is Eugene Godstein's model of the atom?
Eugene Goldstein contributed to the plum pudding model of the atom. This placed negatively charged electrons in a sea of positive charge forming an atom. This came from his experiments with cathode ray tubes and perforated cathodes emitting glows. As cathode rays pass through the perforated holes from anode to cathode, another ray travels in the opposite direction.
What is the plum pudding model and who come up with it?
The plum pudding model suggested that the electrons were dispersed throughout the atom (like chocolate chips in a cookie) and the space was positively charged so that in the end the atom was neutral. Today, people know that the electrons are in a "cloud" around the atom and the protons (and neutrons) are in the nucleus, at the center of the atom.
