WebSo A is the mass number, which is equal to the number of protons, that's the atomic number which we symbolized by Z, plus the number of neutrons. So A is equal to Z plus … WebWhere these particles differ is their mass which is measured in atomic mass units; a proton has 1 mass unit with 1 positive electric charge, a neutron has 1 mass unit with neutral charge, and an electron has a very small (almost immeasurable) mass with 1 negative electrical charge. crystala cf10

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. duty free san ysidro ca
