How is a half life calculated
An exponential decay can be described by any of the following four equivalent formulas: • N0 is the initial quantity of the substance that will decay (this quantity may be measured in grams, moles, number of atoms, etc.), • N(t) is the quantity that still remains and has not yet decayed after a time t, Web21 jun. 2024 · 1. Figure 13.1. 1: Radioactive Decay. During each successive half-life, half of the initial amount will radioactively decay. We can determine the amount of a radioactive isotope remaining after a given number half-lives by using the following expression: (13.1.1) a m o u n t r e m a i n i n g = i n i t i a l a m o u n t × ( 1 2) n.
