Just some important terms regarding chapter 10, Radioactivity.
1. Radioactivity - spontaneous and random emission of radioactive rays from unstable radioactive materials after which they become more stable.
2. Radioactive decay - the breaking up of unstable radioactive nuclei into more stable nuclei with the emission of alpha particles, beta particles, gamma rays.
3. Half-life - The time taken for half the mass of a radioactive material to decay.
4. Radioisotopes - Isotopes with radioactive properties.
5. Nuclear fusion - the splitting up of a nucleus with a big mass into two or more nuclides with the release of energy.
6. Nuclear fission - the combination of small atoms into a larger atom with the release of heat (also known as thermonuclear reaction).
Any corrections, extra info, or anything at all worth sharing, just leave a comment. Thanks.
