Atomic and Nuclear Physics

Nuclear Reactions

Nuclear reactions are reactions between nuclei which involve tremendous amounts of energy and in which mass number and charge are conserved. Alpha and beta decay, fission and fusion are all types of nuclear reactions. Unlike chemical reactions, atomic number is usually changed. 

The different types of nuclear reactions. Contrasts nuclear reactions to chemical reactions. Explains the four main forces of nature; including gravity, electromagnetism, strong, and weak nuclear forces. It also explains how fusion differs from fission.

In nuclear physics, a nuclear reaction is the process in which two nuclei or nuclear particles collide to produce products different from the initial

Alpha Decay

Alpha Decay is a type of radioactivity in which the nucleus of an atom loses an alpha particle. Alpha particles are composed of two protons and two neutrons, so they can also be called He2+ nuclei. The result of alpha decay is the transformation of an element into an element found two boxes before it on the periodic table. Understanding the alpha decay of radioactive substances.

Alpha decay is a type of radioactive (nuclear) decay. This video explains what alpha decay is, how atoms go from stable to unstable, and shows practice problems with examples of alpha decay.
