How did Ernest Rutherford's atomic model change over time?

Who discovered the proton?
Rutherford discovered the proton.After the discovery of the electron, it was realized that there must be positive charge centers within the atom to balance the negative electrons and create electrically neutral atoms. Rutherford's discovery of the nucleus demonstrated that these positive charges were concentrated in a very small fraction of the atoms' volume. In 1919 Rutherford discovered that he could change one element into another by striking it with energetic alpha particles (which we now know are just helium nuclei). In the early 1920's Rutherford and other physicists made a number experiments, transmuting one atom into another. In every case, hydrogen nuclei were emitted in the process. It was apparent that the hydrogen nucleus played a fundamental role in atomic structure, and by comparing nuclear masses to charges, it was realized that the positive charge of any nucleus could be accounted for by an integer number of hydrogen nuclei. By the late 1920's physicists were regularly referring to hydrogen nuclei as 'protons'. The term proton itself seems to have been coined by Rutherford, and first appears in print in 1920.
How would the result of Thomsons experiment change if the beam were a stream of neutrons instead of a stream of electrons?
The number of protons and electrons would be diffrent
How do you change discover into a noun?
The noun that is based on the verb, "discover," would be "discovery" (something that has been discovered) or "discoverer" (someone who has made a discovery).
What is a copper light used for?
A new discovery has indicated that a copper light could reduce the effects of rusting on things such as vehicles. This is an important discovery that could change standard practices on a global level.

How did Rutherfords findings change Thomsons plum pudding model?
Rutherford supposed that the atom had a central positive nucleus surrounded by negative electrons.
How did lord ernest Rutherford change New Zealand history?
he split the atom
How did ernest rutherfords discovery change our world?
it made your mom
How did the discovery by Rutherford change Thomson's theory?
After the discovery of the nucleus positive charge (nucleus) is completely separated from the negative charges (electrons).
How did Ernest Rutherford change the atomic model based on his experimental results?
He placed positive material in the atom's center.
What was ernest Rutherford know for?
established that radioactive elements change into other elements by emitting radiation and discovered the proton.
How did Ernest Rutherford's gold foil experiment change the model of the atom?
After that famous experiment, it was realized that atoms were mostly empty space.
Who discovered a proton?
The proton was discovered in 1918 by Ernest Rutherford. He noticed that when alpha particles were shot into nitrogen gas, his scintillation detectors showed the signatures of hydrogen nuclei. Rutherford determined that the only place this hydrogen could have come from was the nitrogen, and therefore nitrogen must contain hydrogen nuclei. He thus suggested that the hydrogen nucleus, which was known to have an atomic number of 1, was an elementary particle. This he named proton, from protos, the Greek for "first".See answers.com for more informationDiscovery of the ProtonIn the early 1920's after the discovery of the electron, Rutherford and other physicists made a number experiments, transmuting one atom into another.

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.
