WebThe relationship between the decay constant λ and the half-life t1 / 2 is. λ = ln (2) t1/2 ≈ 0.693 t1 / 2. 31.37. To see how the number of nuclei declines to half its original value in one half-life, let t = t1 / 2 in the exponential in the equation N = N0e − λt. This gives N = N0e − λt = N0e−0.693 = 0.500N0. WebHalf-Life formula. You can find the half-life of a radioactive element using the formula: where t 1/2 is the half-life of the particle, t is the elapsed time, N 0 is the quantity in the beginning, and N t is the quantity at time t. This equation is used in the calculator when solving for half-life time. Exponential decay applications

Web10 to the power of X. i.e log (100) = 2. Therefore 10 ^ 2 = 100 which is true :) As a more general rule Log a ( b ) = Log ( a ^ b ) In chemistry log base 10 is used almost all the time so: a will always = 10. edit: Just saw that in this video Log base e is used and not log base 10. i.e the inverse of Log base 10 ( b ) = 10 ^ b.
