What did Rutherford's backward deflection of alpha particle give evidence of an atom's?
Rutherford, Geiger and Marsden discovered the atomic nucleus.
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.
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.
What is atom and who discovered atom?
an atom is the basic unit of a chemical element.
What was the significance of Rutherford's experiment?
he discovered the atom was mostly made up of empty space
What ideas about the atom when new evidence was discovered?
atoms cannot be divided
When was the atom changed when new evidence was discovered?
atoms cannot be divided
What changed about the atom when new evidence was discovered?
atoms cannot be divided
What idea about the atom change when new evidence was discovered?
atoms cannot be divided
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.

Who discovered nuteral atom?
chadwick discovered neutral atom
