GENERAL KNOWLEDGE

Detailed explanation-1: -Nucleosynthesis first occurred within a few minutes of the Big Bang. At that time, a quark-gluon plasma, a soup of particles known as quarks and gluons, condensed into protons and neutrons. After the universe cooled slightly, the neutrons fused with protons to make nuclei of deuterium, an isotope of hydrogen.

Detailed explanation-2: -Nucleosynthesis is the process of creating new atomic nuclei from preexisting nucleons (protons and neutrons).

Detailed explanation-3: -Stellar nucleosynthesis is the process involving nuclear reactions through which fresh atomic nuclei are synthesized from pre-existing nuclei or nucleons. The first stage of nucleosynthesis occurred in the hot, early Universe, with the production of H, He, and traces of Li-7 (primordial nucleosynthesis).

Detailed explanation-4: -Synthesis of the naturally occurring elements and their isotopes present in the Solar System solids may be divided into three broad segments: primordial nucleosynthesis (H, He), energetic particle (cosmic ray) interactions (Li, Be, B), and stellar nucleosynthesis (C and heavier elements).

Detailed explanation-5: -The primordial nuclides were created by Big Bang nucleosynthesis, stellar nucleosynthesis, supernova nucleosynthesis, and by nucleosynthesis in exotic events such as neutron star collisions.
