Why was the neutron the last subatomic particle to be discovered?
no electric charge. the nuclear theory at the time explained the atomic masses by assuming the nucleus contained a number of protons equal to the atomic mass number and enough electrons to cancel the charge beyond that of the atomic number of the element.
What is the electric charge of a neutron?
A neutron doesn't have an electrical charge; its electric charge is zero.
What part of the atom carries no electric charge?
There are three primary subatomic particles: the neutron, the electron and the proton. The electron is negatively charged, the proton is positively charged and the neutron has no charge.
The particle in the nucleus of an atom with no charge?
It is called the nucleus and has a mass unit number of one.
Who discovered the neutrons protons and electrons?
Electron: J. J. Thomson (1897) Proton: Ernest Rutherford (1920) Neutron: James Chadwick (1932) (nucleus : Rutherford 1911)
