Nuclear chemistry

Definition

Nuclear chemistry is the study of the reactions, structures, and properties of atomic nuclei. It explores processes such as radioactive decay, fission, and fusion.

5 Must Know Facts For Your Next Test

1. The stability of a nucleus is determined by the ratio of neutrons to protons (N/Z ratio).
2. Radioactive decay occurs when an unstable nucleus loses energy by emitting radiation.
3. There are three main types of radioactive decay: alpha decay, beta decay, and gamma decay.
4. $$E = mc^2$$ describes how mass can be converted into energy in nuclear reactions.
5. Fission is the splitting of a heavy nucleus into smaller nuclei, while fusion is the combining of light nuclei to form a heavier nucleus.

Related terms

Alpha Decay:

A type of radioactive decay where an unstable nucleus emits an alpha particle (consisting of two protons and two neutrons).

Beta Decay:

A type of radioactive decay where a neutron transforms into a proton with the emission of a beta particle (electron or positron).

$$E = mc^2$$: Einstein's equation that expresses the equivalence of mass and energy; crucial for understanding energy release in nuclear reactions.
