Question

what process is responsible for the creation of rarer element heavier than iron and nickel?

A.STELLAR NUCLEOSYNTHESIS

B.SUPERNOVA NUCLEOSYNTHESIS

C.BIG BANG NUCLEOSYNTHESIS

D.COSMIC RAY SPALLATION​

Answer 1

Explanation:

Carbon is produced by the triple-alpha process in all stars. Carbon is also the main element that causes the release of free neutrons within stars, giving rise to the s-process, in which the slow absorption of neutrons converts iron into elements heavier than iron and nickel.

Answer 2

From the given question the correct answer is :

B.SUPERNOVA NUCLEOSYNTHESIS

Supernova nucleosynthesis is also thought to be responsible for the creation of rarer elements heavier than iron and nickel, in the last few seconds of a type II supernova event. The synthesis of these heavier elements absorbs energy ( endothermic) as they are created, from the energy produced during the supernova explosion.
