What is the role of alpha particle in Rutherford experiment and why he had not taken proton instead of alpha particle?
Ernest Rutherford used alpha particles to bombard a thin gold foil. In the early 1900's, particle accelerators were new and worked on the same principle as the old TV sets (before the plasma and LED ones we have now)
The alpha particle was emitted from radium bromide in to a vacuum tube with a large electric field applied. The alpha, with charge = +2 electrons, was accelerated in the electric field and made to hit the gold foil. By looking at the ways the alpha particles bounced off the foil, Rutherford formulated a model of the atomic structure more or less as we know it today - A dense nucleus and electrons floating around the outside. Basically, the vast majority of the atom volume is vacuum.
He didn't use protons because there is no radioactive substance which emits protons. Only alpha emiitters (2p + 2n), beta elecron/positron emitters and gamme (high energy light) emitters exist naturally.
What else can I help you with?
Who was the inventor of proton - Rutherford or Goldstein?
The proton was first discovered by Ernest Rutherford in 1917 during his gold foil experiment. Wilhelm Wien and Eugen Goldstein contributed to the understanding of the proton, but Rutherford is credited with its discovery.
Who discover proton by 1886?
The proton was discovered by Ernest Rutherford in 1917. Rutherford identified the proton while conducting experiments on the structure of the atom.
When did he see the proton for the first time?
Never. No one has ever actually seen a proton; they're too small.
What is a positively charged subatomic paricle?
A positively charged subatomic particle is a proton. Protons are found within the nucleus of an atom and carry a positive electrical charge.
How Rutherford's experiment led to structure of atom?
Rutherford found that there was a dense center to an atom.
What contribution experiment and reasons of Ernest Rutherford?
E. Rutherford discovered the proton.
What is the positive particle that Rutherford said carried the positive charge in the nucleus of an atom was named?
This particle is the proton.
Who invented the proton?
Ernest Rutherford is generally credited with the discovery of the proton
Who was the inventor of proton - Rutherford or Goldstein?
The proton was first discovered by Ernest Rutherford in 1917 during his gold foil experiment. Wilhelm Wien and Eugen Goldstein contributed to the understanding of the proton, but Rutherford is credited with its discovery.
What subatomic particles did Rutherford discover in 1919?
Rutherford discovered the proton in 1919 during his gold foil experiment. This experiment showed that atoms have a dense, positively charged nucleus at their center. Rutherford's findings revolutionized the understanding of atomic structure.
What particle did Ernest Rutherford discover?
In 1911, Ernest Rutherford discovered the nucleus of the atom. Rutherford was born in New Zealand in 1871 and became known as the father of nuclear physics.
Who is the father of proton?
The father of the proton is Ernest Rutherford. He discovered the proton in 1917 through his gold foil experiment, which demonstrated that the atom contains a dense, positively charged nucleus at its center.
Did Rutherford discover the protons?
Yes, Ernest Rutherford is credited with discovering the proton in 1919 through his gold foil experiment. This experiment involved shooting alpha particles at a thin sheet of gold foil and observing their deflection, leading to the conclusion that atoms have a dense, positively charged nucleus containing protons.
Who discover proton by 1886?
The proton was discovered by Ernest Rutherford in 1917. Rutherford identified the proton while conducting experiments on the structure of the atom.
What particle did Rutherford discover?
Rutherford discovered the positively charged atomic nucleus in 1911 through his gold foil experiment. This experiment revealed that most of an atom's mass and positive charge is concentrated in a small, dense nucleus at the center of the atom.
When did he see the proton for the first time?
Never. No one has ever actually seen a proton; they're too small.
What is a positively charged subatomic paricle?
A positively charged subatomic particle is a proton. Protons are found within the nucleus of an atom and carry a positive electrical charge.
