The rate of disintegration was observed to be `1017` disintegrations per sec when its half life period is `1445` years. The original number of particles are.

The rate of disintegration was observed to be 10^(17) disintegrations per sec when its half life period is 1445 years. The original number of particles are.

If 3//4 quantity of a radioactive substance disintegrates in 2 hours, its half - life period will be

If 3//4 quantity of a radioactive substance disintegrates in 2 hours, its half - life period will be

What parts of a radioactive element is disintegrated in its average life period?

The rate of decay of a radioactive element at t=0 instant 10^(3) disintegrations per second. If the half life of the elements is Is, then the rate of decay after Is will be

Smaller the value of half - life period, greater is the number of atoms that are disintegrating.
