Answer:
Discovery and Features of Subatomic Particles
Protons are positively charged subatomic particles.
The number of protons in an atom is equal to the number of electrons in it.
The discovery of protons is credited to Ernest Rutherford.
Protons can be produced via the removal of an electron from a hydrogen atom.
Answer:
The first subatomic particle to be discovered was the electron, identified in 1897 by J. J. Thomson. After the nucleus of the atom was discovered in 1911 by Ernest Rutherford, the nucleus of ordinary hydrogen was recognized to be a single proton. In 1932 the neutron was discovered.
