What was the significance of Rutherford's experiment?

Rutherford's experiment, known as the gold foil experiment, led to the discovery of the atomic nucleus and the development of the nuclear model of the atom. This experiment provided evidence that most of the atom's mass and positive charge is concentrated in a small, dense nucleus at the center of the atom, with electrons orbiting around it. It revolutionized our understanding of atomic structure.


What did Rutherford's backward deflection of alpha particle give evidence of an atom's?

Rutherford's backward deflection of alpha particles in the gold foil experiment provided evidence of an atom's nucleus. The deflection indicated that the majority of an atom's mass and positive charge is concentrated in a small, dense nucleus at its center, with electrons orbiting around it. This discovery led to the development of the nuclear model of the atom.


What were j.j Thomson ideas called?

In 1897 J.J. Thomson discovered the electron by experimenting with a cathode ray tube.


How did Thomson's discovery change Dalton's atomic theory?

Thomson discovered that atoms can be cut. He found this out while studying rays traveling between charged metal plates in a vacuum tube. He discovered that the rays were consisted of negatively charged particles. He had just discovered electrons. He discovered all of this on a trip from America. Since electrons are so small, he believed that they could only be from inside of the atom. Since Thomson's discovery of the electron, John Dalton's theory that atoms are indivisible had to be changed.


How has the idea of the atom developed and changed over time?

At first we didn't now that the atom existed. It was Einstein who discovered that pollen grains were moving in a glass of water. Why? It was because as he later confirmed that the water particles were pushing it in an unbalanced way. Other scientists later discovered that there are protons, neutrons and electrons in an atom.

What did Sir Ernest Rutherford invent?

Ernest Rutherford discovered that the nucleus of an atom has a positive charge and discovered the evidence to show the electron field surrounding the nucleus in an atom.


Why have scientist change their ideas on the model of the Atom?

There has been more and more observations about the atom that has changed it since then. They revised it to explain the observations.


Why has our idea of what the atom looks like changed so many times?

Our idea of the atom has changed over time as new experimental evidence and theoretical advances have been made. Early models were based on limited information and as technology improved, we discovered more about the structure of the atom. Each new model built upon the shortcomings of the previous one, leading to our current understanding based on quantum mechanics.


Why have scientists revised the a atomic model many times?

they could discover a new atom and it would change


How has the understanding of the arrangement of electrons in an atom changed since the late 1800's?

The electron was discovered by J.J. Thomson in 1897, when he discovered particles inside the atom that contains a negative electric charge. Since then, scientists have learned much more about electrons, and the way they are imagined has changed as well. Niels Bohr established that there was a structure to the way electrons are laid out within the atom, and this discovery has changed the study of physics.
