WebJul 22, 2013 at 20:19. @zoran404 We started by defining temperature to be a measure of the kinetic energy of an atom. As we add energy to the system (heat), it causes the atom to move around, rotate (if it were a molecule), vibrate (if it were a molecule), or the electrons to change orbits. Jul 22, 2013 at 20:23.

WebElectron emission may result when excess neutrons make the nucleus of an atom unstable. As a result, one of the neutrons decays into a proton, an electron, and an anti-neutrino. The proton remains in the nucleus, and the electron and anti-neutrino are emitted. The electron is called a beta particle.
