Term | Definition |
---|---|
Alpha decay/radiation | An alpha particle ejected from an unstable nucleus drops its mass by 4 and its atomic number by 2 |
Beta decay/radiation | A beta particle ejected from a nucleus turns a neutron into a proton, increasing its atomic number by 1 |
Alpha particle | 2 protons and 2 neutrons |
Beta particle | A high energy electron ejected from a nucleus |
Gamma radiation | High energy waves of electromagnetic radiation |
Radioactive isotope | A version of an atom that is not stable and will decay |
Half life | The time it takes for one half of a sample to decay into something else |
Decay chain | A series of decays until a stable isotope is produced |
Parent | An unstable nucleus that decays into something else |
Daughter | The product element from the decay of a radioactive nucleus |
Atomic number | The number of protons in an element's nucleus that determines its identity |
Isotope | A version of an atom with a different mass (same number of protons but different number of neutrons) |
