Difference between Helium and Interstellar medium

Helium vs. Interstellar medium

Helium (from lit) is a chemical element with symbol He and atomic number 2. In astronomy, the interstellar medium (ISM) is the matter and radiation that exists in the space between the star systems in a galaxy.

Similarities between Helium and Interstellar medium

Helium and Interstellar medium have 24 things in common (in Unionpedia): Atom, Big Bang, Big Bang nucleosynthesis, Cosmic dust, Density, Energy level, Gas, Hydrogen, Ion, Kelvin, Matter, Monthly Notices of the Royal Astronomical Society, NASA, Nitrogen, Oxygen, Sodium, Solar wind, Spectroscopy, Speed of sound, Star, Sun, The Astrophysical Journal, Turbulence, Wavelength.

Atom

An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element.

Big Bang nucleosynthesis

In physical cosmology, Big Bang nucleosynthesis (abbreviated BBN, also known as primordial nucleosynthesis, arch(a)eonucleosynthesis, archonucleosynthesis, protonucleosynthesis and pal(a)eonucleosynthesis) refers to the production of nuclei other than those of the lightest isotope of hydrogen (hydrogen-1, 1H, having a single proton as a nucleus) during the early phases of the Universe.
