Neutrons are subatomic particles that are one of the atomic nuclei's most important components.
It is the subatomic particle of an atom that is heavier than a proton but does not have an electric charge.
James Chadwick experimented where polonium's alpha particle radiation collided with beryllium and a surprisingly penetrating type of radiation was formed.
He came to the conclusion that the strangely penetrating radiation was neutrons.
He found that these new particles have no charge and have the same mass as protons are released.
The bombardment elements with neutrons have the potential to penetrate and split nuclei, releasing massive amounts of energy.
Therefore, Neutrons were discovered by James Chadwick.
