What is half-life? Derive the formula for the number of un-decayed atoms. Draw a graph for decaying atoms with time.
The half-life of a substance is the time required for half of the atoms of a radioactive substance to decay. It is a characteristic property of the substance and is used to measure the rate of radioactive decay. Deriving the formula for the number of undecayed atoms: Radioactive decay is exponential: The number of undecayed … Read more
