Question
what is the most abundant element in the universe and why? * 1 point helium because it is the lightest element and easiest to form after subatomic particles boron because it is the lightest element and the easiest to form after subatomic particles hydrogen because it is the lightest element and easiest to form after subatomic particles hydrogen and helium have the same percentage of atoms that make up the universe
Hydrogen is the lightest element (1 proton, 1 electron) and forms easily from subatomic particles (protons, electrons). Big Bang nucleosynthesis produced vast amounts of H. Helium is next, but H is most abundant. Boron is rare. H and He don't have same abundance.
