InterviewSolution

1.	A radioactive nucleus undergoes a series of deacy according to the scheme. `Aoverset(alpha)rarrA_(1)overset(beta^(-))rarrA_(2)overset(alpha)rarrA_(3)overset(gamma)rarrA_(4)` If the mass number and atomic number of `A` are `180` and `172` respectively, what are these numbers for `A_(4)`.A. `56,23`B. `180,72`C. `120,52`D. `84,38`
Answer» Correct Answer - B `Aoverset(beta)rarrA_(1)overset(alpha)rarrA_(2)overset(alpha)rarrA_(3)` `._(72)X^(180)overset(-1e^(0))rarr._(73)X^(180)overset(._(2)He^(4))rarr._(71)X^(176)` `._(71)X^(176)overset(._(2)He^(4))rarr._(69)X^(172)`

The compound unstabel nucleus `._(92)^(236)U` often decays in accordance with the following reaction `_(92)^(236)U rarr ._(54)^(140)Xe +`_(38)^(94)Sr ` + other particles During the reaction, the uranium nucleus 'fissions' (splits) into the two smaller nuceli have higher nuclear binding energy per nucleon (although the lighter nuclei have lower total nuclear binding energies, because they contain fewer nucleons). Inside a nucleus, the nucleons (protonsa and neutrons)attract each other with a 'strong nuclear' force. All neutrons exert approxiamtely the same strong nuclear force on each other. This force holds the nuclear are very close together at intranuclear distances. In the nuclear reaction presented above, the 'otter particles' might be .A. An alpha particle, which consists of two protons and two neutronsB. two protonsC. one proton and one neutronD. two neutrons
`.^(90)Sr` decays to `.^(90)Y` by `beta` decay with a half-life of `28` years. `.^(90)Y` decays by `beta`-to `.^(90)Zr` with a half-life of `64h`. A pure sample of `.^(90)Sr` is allowed to decay. What is the valued of `(N_(Sr))/(N_(y))` after (a) `1h` (b) `10` years ?
