Due to Helium Burning. Helium, being the second most abundant element, reacts with other nuclei to form hevier elements.
He(RAM: 4) + He(RAM: 4) = Be(RAM: 8)
Be(RAM: 8) + He(RAM: 4) = C(RAM: !2) (+ gamma-ray)
C(RAM: !2) + He(RAM: 4) = O(RAM: 16) (+ gamma-ray)
ect..

What is the relationship between hydrogen and other elements?
Hydrogen is basically the motherelement in the universe, hence it being #1. This has of course led to it evolving into different elements, kind of like bacteria evolved into humans in the course of a few billion years, and thus we can always find traces of hydrogen in all other elements, and that's pretty much the relationship between hydrogen and other elements.

What is the least abundant of the eight rock-forming elements that make up most of the continental crust?
The 3 least abundant elements are Francium (Fr), Astatine (At),and Plutonium (Pu). Francium and Astatine come from the decay of Thorium (Th) and Uranium (U), are much more abundant. At any one time in the entire earth's crust there is only 30 grams of Francium and 25 grams of Astatine. Plutonium is only found in Uranium minerals. The amount of Plutonium is microscopic. Here are the 3 least abundant elements. Lowest 3. 89. Francium 90. Astatine 91. Plutonium
