JON CHASE:'Every element is defined by the number of particles in its nucleus. 'Some elements are stable but some elements, such as uranium, 'are unstable and decay by giving off particles or waves.

As some of the heaviest known particles, the W and Z bosons can decay in a myriad of different ways. In the new ATLAS study, physicists focused on seven "decay channels" with the highest discovery ...

Beta decay causes the atomic number of the nucleus to increase by one while the mass number remains the same. Gamma ray emission causes no change in the number of particles in the nucleus ...
