Sagot :

Explanation:

To find the isotope that is expected to be radioactive we have to compare the given isotopes with the ones that we find the in the periodic table.

(A) Ti:

Isotope ----> atomic mass = 48 atomic number = 22

Periodic table ---> average atomic mass = 47.9 atomic number = 22

(B) Sr:

Isotope ----> atomic mass = 88 atomic number = 38

Periodic table ---> average atomic mass = 87.6 atomic number = 38

(C) Os:

Isotope ----> atomic mass = 192 atomic number = 76

Periodic table ---> average atomic mass = 190.2 atomic number = 76

(D) Pu:

Isotope ----> atomic mass = 244 atomic number = 94

Periodic table ---> average atomic mass = 244 atomic number = 94

If we take a look at them we will see that the only one that is different is osmium. The atomic mass of the isotope is 192 amu, that means that this isotope has 2 more neutrons than the average atom of the element. So we can expect that it could be radioactive.

Answer: C. Os
