Question

How are heavier elements like boron (B) and carbon (C), as well as the heaviest elements like gold and silver, primarily created in the universe? Choose the correct processes by name:

A) Fusion in massive stars and nuclear fission in supernovae
B) Fusion in the early universe and nuclear decay in black holes
C) Fusion in red giants and nuclear fusion in white dwarfs
D) Fusion in planetary nebulae and nuclear fusion in comets

Answer 1

Heavier elements like boron (B) and carbon (C), as well as the heaviest elements like gold and silver, are primarily created in the universe through fusion in massive stars and nuclear fission in supernovae.

Step-by-step explanation:

The correct answer is A) Fusion in massive stars and nuclear fission in supernovae.

Heavier elements like boron (B) and carbon (C), as well as the heaviest elements like gold and silver, are primarily created in the universe through fusion in massive stars and nuclear fission in supernovae. In the centers of more massive red giant stars, fusion reactions can build up almost all chemical elements up to the atomic weight of iron. However, elements heavier than iron are synthesized in the explosive environment of supernovae.
