Question 10 • Physics in the Universe

Which definition best describes nucleosynthesis?

Answer
A
the decay of radioactive elements into stable isotopes over time
B
the creation of atomic nuclei through nuclear fusion in stars and during supernovae
C
the process of breaking down heavy elements into lighter elements within stars
D
the formation of molecules from atoms in interstellar space

Explanation

Nucleosynthesis is the process of creating atomic nuclei. It occurs through nuclear reactions, including fusion in stars and reactions during supernovae. Radioactive decay and the formation of molecules are different processes, so the best definition is “the creation of atomic nuclei through nuclear fusion in stars and during supernovae.”
