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. There was no evidence for any of ...

If protons were heavier than neutrons, they would decay to neutrons and there would be no positive charge in the nucleus, consequently no atoms. A Universe without atoms would have no stars ...

Neutrons have no charge. Protons are positively charged. So the relative charge of a nucleus depends only upon the number of protons. The relative charge of a nucleus is the same as its proton ...

In 1930, Pauli speculated that when neutrons form from the fusion of protons, the extra energy is carried away by light-weight, electrically neutral particles. At the time, Pauli did not believe what ...

Neutron stars are some of the densest stellar objects in the universe. Scientists have theorized that the core’s extreme density might allow for the presence of deconfined quark matter.

with its electrical charge +1; and (udd) for the neutron, resulting in an overall neutral electric charge. The difference in configurations also means the neutron is just ever so slightly heavier ...

Protons and neutrons are both composites ... He proposed that another particle must be emitted in the decay, one with no electric charge and a negligible mass. He was proved right – these ...
