At the time of Rutherford's experiment, there were competing ideas of the internal structure of atoms. One idea was the "plum pudding" model where the positive and negative charges of the atom were all mixed up together. The idea that Rutherford had was that all of the positive charge and most of the mass was concentrated at the center of an atom in a region that was its "nucleus."
Rutherford hypothesized that more alpha particles would be deflected if the positive charge and mass of the atom was more spread out, occupying a large part of the volume of the atom.The "plum pudding" model was not the only idea that had been offered for the internal structure of the atom, but none had hypothesized an extremely tiny nucleus with all of the positive charge and virtually all of the Atomic Mass and so none were consistent with his result that relatively few alpha particles were deflected and those that were deflected were deflected a great deal. It did not take long to do the theoretical calculations to show that the experimental results were consistent with a point-like nucleus of positive charge exerting a coulomb (inverse square of distance) force.
The result in now called the Rutherford model of the atom and the type of scattering observed is called Rutherford scattering.
What else can I help you with?
How did Rutherfords model of the atom different from thomsons?
The Rutherford model involve a positive nucleus separated from electrons.
How was Rutherford's atomic model similar with thomsons and bouts model?
Rutherford's atomic model, like Thomson's and Bohr's models, aimed to describe the structure of the atom. Thomson proposed the "plum pudding" model, suggesting that electrons were distributed within a positively charged "soup." Rutherford built upon this by introducing a central nucleus containing positive charge, which led to the planetary model of electrons orbiting the nucleus. While Bohr advanced this further with quantized orbits, all three models emphasized the atom's internal structure and the presence of charged particles.
Which component of the atom is not represented in Rutherford's atomic molecule?
When Rutherford discovered the positive charge in an atom was concentrated in the nucleus, the neutron had yet to be discovered. There are no neutrons in Rutherford's model.
How did Rutherford developed the atom based on the results on his experiment?
Rutherford discovered the atomic nucleus, proposed a nuclear model of the atom also he isolated nitrogen.
What did Rutherford discover or contribute to the model of the atom?
A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles. Also Rutherford discovered atomic nucleus and the proton.
How did Rutherfords model of the atom different from thomsons?
The Rutherford model involve a positive nucleus separated from electrons.
How did Rutherfords findings change Thomsons plum pudding model?
Rutherford supposed that the atom had a central positive nucleus surrounded by negative electrons.
How was rutherfords model similar to thomsons model and how was it different?
Rutherford's model was similar to Thomson's model in that both described atoms as having a positively charged center (nucleus) surrounded by negatively charged electrons. However, Rutherford's model differed in that he proposed that the majority of an atom's mass and positive charge was concentrated in the nucleus, with electrons orbiting around it, while Thomson's model suggested that the positive charge was uniformly distributed throughout the atom.
How did Ernest Rutherford change the 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.
Did Ernest Rutherfords results fit with J.J Thomsons view of the atom?
Thomsons model is sometimes called the plum pudding model as he envisaged a soup of positive charge with negative charges, by then already called electrons swimming round. He came up with this idea in 1904."the atoms of the elements consist of a number of negatively electrified corpuscles enclosed in a sphere of uniform positive electrification"Rutherford following on from the famous scattering experiment with gold foil and alpha particles proposed that the positive charge was concentrated in a central nucleus.
What is Rutherford atomic model?
nuclear atom
The nuclear model of the atom was proposed by?
Rutherford
How did Rutherford's work help form the present day model of the atom?
The atomic model of Rutherford was a step in the historical development of the today concept of an atom.
What was JJ Thomsons 1904 model called?
JJ Thomson's 1904 model was called the "plum pudding model." This model described the atom as a sphere of positive charge with electrons embedded throughout, like plums in a pudding. It was later replaced by the more accurate Rutherford model.
Whose model was called planetary model of the atom?
its was Ernest Rutherford who proposed the planetary atomic model
Who presented thenuclear model of atom first?
Rutherford presented the nuclear model of atom first.
What is the difference between Thomsons atomic model and Rutherfords atomic model?
Thomson's model was the "Plum Pudding model" because it had electrons "floating" around in the ball, but Rutherford's model shows the electron shells, the nucleus, and the molecular particles: neutron, proton, and electron. Hope this helps!
