Nuclear Decay

Watch these videos, which present four different types of nuclear decay. In addition to alpha and beta decay, gamma and positron emission can occur. The positron is a particularly interesting particle. It is an example of anti-matter, as it is an anti-electron. In the case of positron decay, there is no change in mass number, but the atomic number decreases by one. The second video explains how to write nuclear equations for alpha, beta, and gamma decay.
