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.

∙ 14y agoIt is hard to give credit to one single person. Here are some of the important people and their discoveries that led up to this model:
Ernest Rutherford found that the atom is mostly empty space with a very small but heavy nucleus in the center.
Niels Bohr had a model of atomic structure in which electrons orbited the nucleus in a circular orbit -- this was wrong (the orbits are not circular at all), but he had the idea that electrons were moving around the nucleus, which is true.
Werner Heisenberg was really the person that determined that the only way to describe the location of electrons is as a probability distribution, and this led to the idea of an "electron cloud" where you can only talk about the relative probability of find an electron in a certain volume. This is really what quantum mechanics is all about! Other important people involved in the development of quantum mechanics were Erwin Schrodinger and Louis de Broglie, among others.
See the Related Questions links for more information about each of these famous scientists!
EDIT Rutherford and Bohr contributed to earlier models of the atom, which the cloud model built upon. Many many more scientists also contributed to the cloud model.

∙ 7y agoThe Bohr-Rutherford or Rutherford-Bohr model was developed by Niels Bohr and Ernest Rutherford. But physicist Erwin Schrödinger is often credited with the "quantum state" theory of the electron, where electrons do not occupy fixed orbits but rather an energy state around an atom.

∙ 12y agoErwin Schrödinger was the German scientist who invented the electon cloud theory that we believe in today.He was assisted by another German scientist but i cant remember his name.It dosent matter though because Schrödinger was really the main person.I read it out of my text book so this answer should be pretty accurate.Hope this helps.! :D

What is the specific amount of energy an electron has?
An electron has no specific amount of energy. According to Bohr's Model of hydrogen atom, the energy of an electron in a shell is given by: E=-13.6x Z2/n2 E.V. Where Z is the atomic number of the atom, n is the shell number and E.V. is electron volt, the unit for energy 1E.V. = 1.6 x 10-19 J. But the Bohr's model was rejected and quantum mechanical model of an atom came into force where n=principal quantum number and l=Azimuthal quantum number are used to determine the energy of an atom. 'n' determines the energy to a larger extent and 'l' to a little extent.
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 does Dalton's model of the atomic theory differ from the models that came before it?
You did not specify but seeing as my course is currently specifying in this field I have at least minimalist credentials in laments... Older models had electrons following an orbit which is frankly not true, modern day electron cloud models show that they are roughly here whereas for instance, the Bohr model shows them following a strict orbit
Who created the first model of a atom?
The Australian scientist, M Vella came up with this model in the late 1900's.
How did Ernest Rutherford change atomic model?
Before Rutherford, scientists assumed that the atom was a single particle. Rutherford presented his revolutionary, physical atomic model that suggested an atom consists of a central charge (the term 'nucleus' was coined after Rutherford's model was presented) that is surrounded, presumably, by a cloud of orbiting electrons. He showed that most of an atom's mass was located in the atom's nucleus. Rutherford's model was later improved upon by Niels Bohr, father of the Bohr-model. Rutherford made no connection to an element's atomic number and the number of protons within an atom's nucleus; however, his atomic model paved the way for the discovery of this correlation only a couple years after his model was designed.
Which scientist came up with the Electron cloud model of the atom?
Bohr-Rutherford
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'.
Which scientist came up with the electron cloud?
Bohr-Rutherford
Why is the quantum theory important to the history of the atom?
it became the basis for all chemistry from then on

John Dalton
What is the best describe the current model of an atom?
The current model of an atom is best described by the Solar System. The planets represent electrons while the sun represents the nucleus.
What areas did Niels Bohr make contributions in?
He made a model of the atom, with electrons circling the nucleus.

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.
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.
