Nuclear Chemistry
| Term | Definition |
|---|---|
| Positron | A positive electron |
| Alpha Radiation | Alpha particles (two protons and two neutrons) are released. Atomic number is lowered by 2 and mass lowered by 4. Least penetrating power. |
| Beta Radiation | A neutron is converted to a proton, and an electron is released. Atomic mass stays the same and atomic number increases by 1. Medium penetrating power. |
| Gamma Radiation | When a high energy photon is released. It doesn’t have a charge. Has the most penetrating power. |
| Positron Radiation | When a proton converts to a neutron and also emits a positron. Atomic mass remains the same and Atomic number decreases by one. |
| Radioisotope | An unstable version of an element that releases radiation. It breaks down to become more stable. |
| X-Ray | Similar to gamma rays, a form of high energy electromagnetic radiation. Less energy than gamma rays. |
| Half-Life | The time it takes for a radioactive atom to decay into another element. |
| Transmutation | the process of converting one chemical element into another by changing the number of protons in its nucleus |
| Penetrating Power | The ability of radiation to pass through matter |
| Radioactive Decay Series | A series of nuclear reactions that begins with an unstable nucleus and makes a stable nucleus. |
| Nuclear Fission | The splitting of a nucleus. Releases a lot of energy (Atomic Bomb) |
| Nuclear Fusion | The combining of atomic nuclei. Gives off the most energy. (the sun) |
