Describe in basic terms how elements were/are formed during the big bang (including the reasons why only H/He formed abundantly)‚ during normal stellar operation (including why some elements such as Si and Fe were formed more abundantly)‚ and during supernova processes/explosion Big bang only thing that forms out of the big bang is the nuetrons. Protons plus electrons = hydrogen. Hydrogen fuses the helium. There are no stable atoms with 5 or 8 nucleons (hydrogen would have 5‚ helium would have
