Which characteristic is most likely found in a nuclide that is radioactive and synthetic?
a. an atomic number of 30
b. a mass number of 30
c. an atomic number of 94
d. a mass number of 94

Explanation:

Radioactivity is the emission of radiation or particles caused by the spontaneous disintegration of atomic nuclei.

This process generally occurs in heavy nuclei because in these nuclei the neutron-proton ratio deviates from unity significantly.

Plutonium has a atomic mass of .It is heavy enough for radioactivity

Plutonium with atomic number is radioactive and synthetic.

first one is the correct answer

answer: they produce more slow than unicellular organisms.
