CHEMISTRY CALCULATORS
Half-Life Calculator
Effortlessly calculate half-lives of radioactive isotopes for chemistry enthusiasts.
What is the Half-Life Calculator & How does it work?
The half-life of a radioactive isotope is the time required for half of its initial quantity to decay. This concept is fundamental in understanding radioactivity and has applications in various fields such as nuclear physics, archaeology, and medicine.
The formula to calculate the amount of a substance remaining after a certain period is given by:The decay constant λ is related to the half-life T1/2 by the equation:
The formula to calculate the amount of a substance remaining after a certain period is given by:
N(t) = N_0 \times e^{-\lambda t}
N(t) = Amount of substance at time t
N0 = Initial amount of substance
λ = Decay constant
t = Time elapsed
N0 = Initial amount of substance
λ = Decay constant
t = Time elapsed
\lambda = \frac{\ln(2)}{T_{1/2}}
T1/2 = Half-life of the isotope
Parameters
Remaining Amount—
