Nuclear Chemistry

1. force that causes particles or bodies to repel one another, as from having the same electric charge or magnetic polarity
4. capture radioactive decay process by which an atom's inner orbital electron is absorbed within the nucleus
5. two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nucleus
6. decay a nuclear decay process where an unstable nucleus changes to another element by shooting out a particle composed of two protons and two neutrons
7. decay process by which an unstable atomic nucleus loses energy by radiation
8. reaction atoms attain stability through changes in the nucleus
12. decay a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide
13. process by which an unstable nucleus spontaneously emits high energy particles from the nucleus in order to attain a more stable nuclear state
14. of stability a plot of the number of neutrons versus the number of protons for stable nuclei reveals that the stable isotopes fall into a narrow band

2. force an attractive or repulsive force between particles that are caused by their electric charges
3. force a force that acts between the protons and neutrons of atoms
9. the production and discharge of something, especially gas or radiation
10. decay a type of radioactivity in which some unstable atomic nuclei dissipate excess energy by a spontaneous electromagnetic process
11. reaction atoms attain stability by losing, gaining, or sharing electrons
