Which subatomic particles are known to have no charge?
The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge.
When and who discovered subatomic particles?
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.
Which scientist discovered the subatomic particle proton?
Ernest Rutherford
History
| Particle | Composition | Discovered |
|---|---|---|
| alpha particle α | composite (atomic nucleus) | Ernest Rutherford (1899) |
| Photon γ | elementary (quantum) | Ernest Rutherford (1899) as γ rays |
| Proton p | composite (baryon) | Ernest Rutherford (1919, named 1920) |
| Neutron n | composite (baryon) | James Chadwick (1932) |
Who was the first person to discover the neutron?
An English physicist Sir James Chadwick discovered Neutron in 1932. Neutron are one of the three subatomic particles that constitute the structure of an atom. The other two particles are protons and electrons.
When did Sir James Chadwick discover the neutron?
An English physicist Sir James Chadwick discovered Neutron in 1932. Neutron is one of the three subatomic particles that constitute the structure of an atom. The other two particles are protons and electrons.
How did James James come up with the name neutron?
James noticed that the new radiations scattered the protons in a different angle and were not gamma radiations but rather radiation that had unknown particles with a net neutral charge and mass equal to that of the protons. He named it neutron and also received the noble prize for this in 1935.
