The incoming neutron hitting the nucleus causes a proton to shoot out of the nucleus, just as a cue ball on a pool table ... emitting an electron (with a charge of -1) in the process.

In 1932, another British physicist, James Chadwick, discovered the neutron, another particle located within the nucleus. With the electron, proton, and neutron, scientists thought they had found ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

For the first time, scientists have successfully mapped the shape of an electron while it moves ... Inside an atom, it works ...
