Did Thompson's experiment led to discovery of the neutron?
no
How do alpha particles behave when beamed at thin metal foil?
When alpha particles are beamed at thin metal foil, they mostly pass through the foil with some deflected at small angles due to interactions with the metal atoms. This experiment led to the discovery of the nucleus by Ernest Rutherford in 1911.
Which scientist's experiments led to the discovery of protons?
Ernest Rutherford's experiments on the scattering of alpha particles by a thin sheet of gold foil led to the discovery of the atomic nucleus and the realization that atoms contain a central, positively charged nucleus called the proton.
Why did most of the alpha particles pass through the gold foil?
Most of the alpha particles passed through the gold foil because atoms are mostly empty space, and the alpha particle is small enough to pass through without colliding with the dense nucleus. This led to the discovery of the nucleus, as a few alpha particles were deflected or bounced back, indicating a dense, positively charged center in the atom.
Who identified cathode rays as subatomic particles?
J.J. Thomson is credited with identifying cathode rays as streams of negatively charged subatomic particles, which were later named electrons. His experiments with cathode ray tubes led to the discovery of the electron and contributed to the development of the atomic theory.
When positively charged particles bounced back from the foil Rutherford called this?
Rutherford called this phenomenon the "scattering of alpha particles" which was a key observation that led to the development of the nuclear model of the atom.
What happened to the alpha particles as they hit he gold foil?
When alpha particles hit the gold foil in the famous Rutherford experiment, most of them passed straight through, while a few were deflected at large angles, indicating that the atom was mostly empty space with a dense positively charged nucleus. This unexpected result led to the discovery of the atomic nucleus.
In Rutherfords gold foil experiment shown in Figure 4-1 alpha particles that bounce straight back from the foil have struck in the gold atoms?
No, they struck the nucleus of the atom. Since the alpha particles are positively charged and nucleus is positively charged as well, they repelled each other and alpha particles are repelled back
In Rutherford's gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
Who is the father of neutron?
Sir James Chadwick is credited with the discovery of the neutron in 1932. His experiments on the collisions of alpha particles with beryllium led to the identification of the neutron as a fundamental particle found in the nucleus of atoms.
What effect does humidity have on alpha particles?
Alpha particles can be absorbed by water.
Where could one locate Alpha particles?
Alpha particles are most commonly found when alpha decay occurs. An alpha particle is emitted during alpha decay. Further information about alpha particles can be found on the Wikipedia website.
