ANSWER:
Problem 41 EPredict a likely mode of decay for each unstable nuclide.a. Mo- 109b. Ru-90c.P-27d.Rn-196 Step by step solutionStep 1 of 5To find out the which radioactive decay a nuclide undergoes to become stable, we have to findout the ratio of neutron and proton (N/Z). Figure 20.5 had assigned specific values for N/Z withatomic number in which the molecule will be stable. If N/Z value is high, then the nuclide willundergo beta decay and will reduce the mass number. IF N/Z value is low, then the nuclide willundergo positron emission or electron capture.
