CHEM 100 Chapter 10: Notes
Document Summary
Reactions that change the atomic nuclei into energy. Ex: sun combining h2 to form he. The study of nuclear reactions with emphasis on their uses in chemistry. Lets review the structure of the atom. : number of protons plus number of neutrons in an element. : atoms with the same atomic number but different mass numbers. A nucleus containing a specified number of protons and neutrons. Emission of ration is one way unstable nucleus transforms to a stable one. Emitted radiation is a carrier of excess energy. Changed the way you look at the reactions. Give up a particle to get something else. Particle you give up is alpha particle. Positron has the same mass as an electron but opposite charge. Capture of an electron by the nucleus from the electron cloud surrounding the nucleus. The loss of radioactivity when a radioactive element emits nuclear. Radioactive decay in nature results in the creation of daughter nuclei.
