APES MATH TIPS for the AP Exam of the most important math skills, because you will have to fit numbers with units together Determine half-life without. The formula for a half-life is T1/2 = ln(2) / λ. In this equation, T1/2 is the half-life. The ln(2) stands for the natural logarithm of two and can be estimated as 0.693, and the λ is the decay constant. The decay constant for a given element is determined experimentally by measuring the decay. A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay. For example, if the half-life of a 50.0 gram sample is 3 years, then in 3 years only 25 grams would remain. During the next 3 years, 12.5 grams would remain and so on. To answer this question.
