WebBased on the last equation, half life is the value of t for which N=N0/2. If we replace this in equation 3, we obtain: N02=N0e-t1/2. (4) Solving this equation for t1/2 yields: t1/2=ln (2) (5) This means we can determine an element’s half life by measuring its decay constant from experimental data.
