When a nucleus of a given isotope decays, it

Question options:

cannot produce a daughter with a lower mass number.

cannot produce a daughter with the same mass number.

always produces a daughter with a lower mass number.

always produces a daughter with a higher mass number.

cannot produce a daughter with a higher mass number.

Solutions

Expert Solution

Answer: cannot produce a daughter with a higher mass number

Whenever the nucleus of a given isotope decays, the daughter can have the same or lower mass number. Thus, the given first 2 statements are not correct. But it is not true always, so 3rd option is also true. However, the daughter nucleus cannot have higher mass number, so the 4th option is incorrect and the last option is correct.

Given data: Ln2=0.693, 1Ci=3,7.1010 des/s 140Ba radionuclide with half-life Tp=306 hours decays to its daughter 140La with a half-life of Td=40.3 hours and to stable granddaughter 140Ce. The scheme of the decay is illustrated as follows: 140Ba → 140La → 140Ce The parent, 140Ba, has an initial activity of A0=5mCi. The initial number of nuclei (at t=0) of the daughter 140La is N0 = 0, and tm is the time when the daughter activity reaches its maximum value.  The equations of...
