WebAnswer (1 of 8): It is not ‘made’ in the sense of we humans causing it to come into existence. It needs to be mined. There are a few long-lived radioactive isotopes inside the Earth that produce it when they decade by an alpha decay process. These alpha particles are nuclei of He-4 and they carry... WebThose stars have [Fe/H] values no larger than −1.5 and sometimes as low as −3.5. Called metallicity, [Fe/H] indicates the overall abundance of elements beyond hydrogen and helium, up to and including iron. Also, r-I and r-II stars presumably formed early in cosmic history, whereas the solar system is a relatively youthful 4.6 billion years old.

Helium has a valence of zero and is chemically unreactive under all normal conditions. It is an electrical insulator unless ionized. As with the other noble gases, helium has metastable energy levels that allow it to remain ionized in an electrical discharge with a voltage below its ionization potential. Helium can form unstable compounds, known as excimers, with tungsten, iodine, fluorine, sulfur, and phosphorus when it is subjected to a glow discharge, to electron bombardm… WebInside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium. This fusion process occurs inside … body builders working out

WebChemical Elements. Chemical elements are substances composed of only one type of atom and they cannot be broken down further. Chemical elements are the simplest forms of matter and each one is assigned a specific atomic number. Check out these articles on chemical elements. WebHelium-3, also written as 3 He, is a light isotope of helium having 2 protons but only one neutron and an atomic mass of 3. The existence of Helium-3 was first proposed in 1934 by the Australian nuclear physicist Mark … Web14 dec. 2024 · Some of the elements we know, like carbon and oxygen, are made in stars, but others — including all hydrogen, most helium, and a bit of lithium — were forged nearly 14 billion years ago ... bodybuilders wrestle
