Web23 Jan 2024 · Calculation: Now, Given value of half life period = 1600 years. Also, we have the expression of half-life as. λ t 1 / 2 = l n 2 λ -- (1) Now, If 75 % got decay, we will be left with 25% of total sample nucleus. If the time required for the process is t', then. N = N 0 / 4. λ l n ( N 0 / 4 N 0) = − λ t '. WebThe half-life of radium is 1600 years.
