The activity of curie for given set of compounds with given mass should be calculated. Concept Introduction: Half-life: It can be defined as the time taken to decay half of the initial amount of the given element. Decay constant (k): It is the constant value which gives the ratio of the number of atoms present in the substance that decays in given time period compared with the total initial number of atoms present. The relationship between half-life period and the decay constant are depicted as follow Half-life: It can be defined as the time taken to decay half of the initial amount of the given element. Decay constant (k): It is the constant value which gives the ratio of the number of atoms present in the substance that decays in given time period compared with the total initial number of atoms present. The relationship between half-life period and the decay constant are depicted as follow t 1 2 = 0.693 λ .
