Helium 3 atomic number
WebHelium-4 is a particularly stable nucleus hence it has a high binding energy per nucleon Carbon-12 and oxygen-16 can be considered to be three and four helium nuclei, respectively, bound together At high values of A : The general binding energy per nucleon is high and gradually decreases with A WebHelium (pronunciation: HEE-lee-em) is a colorless, odorless element classified as a non-metal, belonging to the group of inert gases in the periodic table and is represented by the chemical symbol He [1, 2, 3]. It is a monoatomic gas that forms weak diatomic molecules only at temperatures close to -273.15 °C or “the absolute zero” [4].
