beta decay
In nuclear physics, beta decay is a type of radioactive decay in which a beta ray, and a respective neutrino are emitted from an atomic nucleus
half-life
Half-life is the time required for a quantity to reduce to half its initial value
molar mass
In chemistry, the molar mass M is a physical property defined as the mass of a given substance divided by the amount of substance
atomic nucleus
The nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment
electron shell
In chemistry and atomic physics, an electron shell, or a principal energy level, may be thought of as an orbit followed by electrons around an atom's nucleus
amu
The unified atomic mass unit or dalton is the standard unit that is used for indicating mass on an atomic or molecular scale
subatomic particles
In the physical sciences, subatomic particles are particles much smaller than atoms
molecular weight
Molecular mass or molecular weight is the mass of a molecule
