Helium how many protons
WebHelium is an element, so to make an element you have to combine protons and neutrons which is much much harder than it sounds. There are only 2 environments that commonly make elements. First is inside stars where the pressure and heat are unimaginably high that the protons and neutrons flu around in massive soup until they can stick to each other. WebHelium Helium is the second element of the periodic table and thus is an atom with two protons in the nucleus. Most Helium atoms have two neutrons in addition to the protons. In its neutral state, Helium has two …
