A hydrogen atom has one proton as the nucleus ... to locate the exact position of an electron, but the electron cloud shows the region where an electron is most likely to be. When the plastic strip is ...

according to which the proton spends a certain fraction of its life in a virtual state as a neutron plus a free positive electron and neutrino. Since the electron has a large magnetic moment ...

Beta (\(\beta^-\)) decay is the release of an electron by the change of a neutron to a proton. The neutron (charge = 0) is made up of one up quark (charge = \(\frac{2}{3}\)) and two down quarks ...

For example ... a charge of only 2. Rutherford also put out the idea that there could be a particle with mass but no charge. He called it a neutron, and imagined it as a paired proton and electron.

All radioactive atoms will eventually decay, or change, in some way. When a carbon-14 atom decays, one of its eight neutrons turns into a proton, emitting an electron (with a charge of -1 ...
