What is beta decay?

Back

Beta decay is a type of radioactive decay in which an unstable atomic nucleus transforms into a more stable one by emitting a beta particle (an electron or a positron).

What is the significance of half-life in nuclear chemistry?

Back

Half-life is the time required for half of the radioactive atoms in a sample to decay, indicating the stability and decay rate of the isotope.
