Question

What is the process of nucleosynthesis?

Answer 1

Nucleosynthesis is the process of creating new atomic nuclei from preexisting nucleons (protons and neutrons).

Explanation:

Nucleosynthesis, production on a cosmic scale of all the species of chemical elements from perhaps one or two simple types of atomic nuclei, a process that entails large-scale nuclear reactions including those in progress in the Sun and other stars.

Nucleosynthesis is the process of creating new atomic nuclei from preexisting nucleons (protons and neutrons).

The primordial preexisting nucleons were formed from the quark-gluon plasma of the Big Bang as it cooled below ten million degrees.

This first process may be called nucleogenesis, the genesis of nucleons in the universe.

The subsequent nucleosynthesis of the elements (including all carbon, all oxygen, etc.) occurs primarily in stars either by nuclear fusion or nuclear fission.
