WebStellar nucleosynthesis is the process by which elements are created within stars by combining the protons and neutrons together from the nuclei of lighter elements. Fusion inside stars transforms hydrogen into helium, heat, and radiation. Heavier elements are created in different types of stars as they die or explode. WebBoth these conditions have been discussed below: Case 1: Using 4 protons, 5 neutrons, and 4 electrons: In this case, we can get a neutral and stable beryllium atom. The atomic mass of such specie is found to be 9 with net zero charge. It has 4 protons in the nucleus, 5 neutrons in the nucleus, and 4 electrons residing in orbitals.
