Q 5 ExerciseExpert-verified
Which stable nuclei have a diameter of 7.46 fm?
Therefore, chemical element who has stable isotope of A = 30 is silicon Si.
We have to find value of A from next formula:
Chemical element who has stable isotope of A = 30 is silicon Si.
The rate at which a radioactive tracer is lost from a patient’s body is the rate at which the isotope decays plus the rate at which the element is excreted from the body. Medical experiments have shown that stable isotopes of a particular element are excreted with a 6.0 day half-life. A radioactive isotope of the same element has a half-life of 9.0 days. What is the effective half-life of the isotope, in days, in a patient’s body?
