Balancing Nuclear Equations
Another particle that a nucleus can emit during a decay is a positron (01e
). A positron is just like any other electron, except it has a positive charge (weird, huh?). For example, Carbon-11 decays by positron emission:
So where are all of these positrons? Since positrons are anti-matter, they don't exist for very long. As soon as they collide with a normal electron (which are everywhere
), they destroy each other and produce energy in the form of gamma rays.
