Half Life Formula

The half-Life formula is an equation we use to calculate the rate of disintegration of unstable atomic nuclei which leads to the emission of alpha (α), beta (β), or gamma (γ) particles. The half-life formula is written as T1/2 = (0.693) / λ, or T1/2 = ln(2) / λ, or T1/2 = (Loge2) / λ What is Half-Life? The half-life of a radioactive element is the time it takes half of the atoms initially present in the element to disintegrate or decay.
