Half Life And Rate Of Decay MDCAT Quiz with Answers
Half-Life The time required by half of the atoms of a sample containing a radioactive substance to decay is called half-life. This concept is an essential part of nuclear physics and describes radioactive decay in a predictable manner. The rate of decay is determined by probabilities that a single atom undergoes decay in a given time frame, which remains constant for a given radioactive isotope. The process of decay in an exponential mode shows a decrease in the quantity of undecayed nuclei by half on every consecutive half-life. The rate of decay is usually expressed in terms of the decay constant, λ, which is linked with half life by the relation
