Question

Calculate half life of radioactive elements

Answer 1

Radioactive Half-Life Formula. Aradioactive half-life refers to the amount of time it takes for half of the original isotope to decay. For example, if the half-life of a 50.0 gram sample is 3 years, then in 3 years only 25 grams would remain. During the next 3 years, 12.5 grams would remain and so on..

Answer 2

X=a/2
2.303/t(1/2)xlog a/(a-a/2)=k1
2.303/t(1/2)=log 2=k1
t1/2=2.303/k1 x log 2
t1/2=0.693/k1
