Ernest Rutherford discovered the nucleus by conducting the famous gold foil experiment in 1909. He bombarded alpha particles onto a thin gold foil and observed that some particles were deflected, leading him to conclude that atoms have a dense nucleus at their center.

Why is this so that million of alpha particles bombarded on beryllium will produce only 30 neutrons?
When alpha particles are bombarded on beryllium, the process that occurs is known as the (α, n) reaction. In this reaction, the alpha particle collides with a beryllium nucleus, causing it to absorb the alpha particle and become an unstable nucleus. This unstable nucleus then decays, emitting a neutron. The probability of this reaction occurring is relatively low, which is why not all alpha particles result in neutron production.
What was rutherfords experiment?
he shot tiny alpha particles throug a piece of gold foil. -Apex
What did James Chadwick use to discover neutrons?
James Chadwick used a series of experiments involving alpha particles and beryllium to discover neutrons in 1932. By observing the scattering of these particles, he was able to infer the existence of neutrons, which are electrically neutral particles found in the nucleus of atoms.
Alpha particles ejected from the nucleus travel at the speed of light?
Alpha particles are emitted from the nucleus at high speeds, typically around 5-10% of the speed of light. They move with such energy due to the strong repulsive force between the positively charged alpha particle and the remaining nucleus.
Does alpha particles have less mass the beta particles?
An alpha particle is two protons and two neutrons (same as a Helium nucleus) so when a nucleus ejects an alpha it will defintely have less mass. Also it will be a new element because it has two less protons.

Why the alpha particles could not smash the nucleus apart?
The alpha particle is positively charged (as is the nucleus) and is heavy compared with the neutron that is neutral and lighter than the alpha particle.Another viewpoint:It depends what experiment the question is about. For example, over a hundred years ago, Rutherford bombarded gold foil with alpha particles and some "bounced off" what we now call the nucleus of the atoms. However, about ten years later he did experiments in which alpha particles did indeed "split" atomic nuclei. So, sometimes alpha particles can certainly smash a nucleus apart.
Can transmutation reactions occur when the neutrons of various elements are bombarded by alpha particles?
yes
When atoms of beryllium are bombarded with alpha particles an atom of carbon is produced and a neutron is emitted What kind of nuclear reaction occurred?
Nuclear Fission. The Nucleus of the Atom has been split apart.

When ununoctium bombarded with alpha particles new element is formed or not?
This reaction is not known up today.
Which element on bombarding with an alpha particle gives Oxygen 17?
Nitrogen (N-15) bombarded with an alpha particle results in Oxygen-17 due to a nuclear reaction called alpha capture.

When potassium-39 is bombarded by neutrons chlorine-36 is produced what other particles are emitted?
An Alpha particle
Are alpha particle negative or positive?
An alpha particle is a helium nucleus; it has a charge of +2.
Which particles is similar to a He nucleus?
The so-called alpha particles ARE helium nuclei.
Type of nuclear decay consisting of a helium nucleus?
Alpha decay. Alpha particles are the same as a helium-4 nucleus.
