WebOf all the elements, helium is the most stable; it will not burn or react with other elements. Helium has the lowest melting and boiling points. It exists as a gas, except under extreme conditions. At temperatures near absolute zero, helium is a fluid; most materials are solid when cooled to such low temperatures. WebHelium has a very low viscosity, a high diffusion coefficient, and the smallest atom of any element. These characteristics make helium very hard to contain. If a system has a leak, helium will escape. Helium gas is therefore used to test for leaks in high vacuum systems, fuel systems, and other containments.

WebFor stable elements, there is usually a variety of stable isotopes. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. Mass numbers of typical isotopes of Helium are 3; 4. Atomic Mass of Helium. Atomic mass of Helium is 4.0026 u. The atomic mass is the mass of an atom. In the perspective of quantum mechanics, helium is the second simplest atom to model, following the hydrogen atom. Helium is composed of two electrons in atomic orbitals surrounding a nucleus containing two protons and (usually) two neutrons. As in Newtonian mechanics, no system that consists of more than two particles can be solved with an exact analytical mathematical approach (see 3-body problem) and helium is no exception. Thus, numerical mathematical meth… cx core pin
