Elements 2: Helium
Helium is the first compound element, and the first of the group called the noble gases. This name was chosen because this group (column in the periodic table) is chemically unreactive under conditions that favor human life. Since Helium was among the first-born atoms, it is very abundant in the universe. Though rare on earth, Helium’s universal abundance is second only to that of Hydrogen.
One can imagine that at the reality of a larger than primal atom, the road is open for more complex atoms, and so it was: in the heavier stars, thermonuclear fission processes produced heavier elements still. In fact, there is not a single heavier atom that was not created at some point in time in some star. All matter is stardust. All heavier atoms are the product of nuclear fission in stars.
We ourselves are the children of stars become aware.
