TermDefinition
Nuclear ForceA nonelectrical, nongravitational force that holds together a nucleus.
Alpha DecayThe nucleus emits a particle that has the same constitution as a helium nucleus, with 2 protons and 2 neutrons. Are the least penetrating of the products of nuclear decay. Seen mainly in very large nuclei (usually with atomic numbers of 60+)
When a Nucleus Undergoes Alpha Decay...Subtract 4 from the mass number and 2 from the atomic number.
Beta DecayEmits a particle identical to an electron. In addition, the nucleus changes a neutron into a proton.
When a Nucleus Undergoes Beta Decay...Leave the mass number as is, and add 1 to the atomic number.
Positron EmissionEmits a particle like an electron with a positive charge. In addition, the nucleus changes a proton into a neutron.
Electron CaptureThe nucleus captures a low energy electron and combines it with a proton to form a neutron.
When a Nucleus Undergoes Positron Emission...Leave the mass number as is, and subtract 1 from the atomic number. ("B")
When a Nucleus Undergoes Electron Capture...Leave the mass number as is, and subtract 1 from the atomic number. ("e")
Gamma RaysElectromagnetic radiation that have no mass or charge. Usually accompanies other forms of nuclear decay, and are most penetrating of the nuclear decay products.
If an Isotope's Mass Number > Atomic Weight...Nucleus will try to gain protons and lose neutrons. Can expect beta decay.
If an Isotope's Mass Number < Atomic Weight...Nucleus will try to lose protons and gain neutrons. Can expect electron capture or positron emission.
Half-LifeTime for half of the substance to decay
Mass DefectDifference in mass of the sum of masses of protons and neutrons, and the mass of the nucleus. The mass lost this way is released in the form of energy.
E = mc^2Relationship between mass and energy
Binding EnergyEnergy required to decompose the nucleus (result of a mass defect) back into protons and neutrons
