Half-life equation calculus
WebFormula for Half-Life in Exponential Decay –. N ( t) = N 0 ( 1 2 t t 1 2) N ( t) = N 0 e − t τ. N ( t) = N 0 e − λ t. N 0. 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, t 1 2. WebAfter each subsequent half-life of 20 hours the number of radioactive nuclei and the original radioactivity of 800 units are divided into half. By integration of this relation and applying the boundary conditions that at in the beginning t = 0 and N = N0 we obtain: ln(N/N0) = t (6.4) and subsequently the equation of exponential decay: N = N0e t ...
