What is the chemical composition of the universe?
Q. We know that the sun contains mostly hydrogen, and that it fuses into helium to create massive amount of energy. We also know that space contains trace amounts of hydrogen (H). Where does the mariad of chemical compounds on Earth come from - from H, all the way to Pb and the other large elements? Why is there an island of such a high concentration of different elements on the Earth while the vast majority of the rest of the world is simply hydrogen? Where did these simple and complex chemicals come from?

A. The same as it was 12 billion years ago. In round figures 73% hydrogen, 25% helium, the rest is lithium, boron and heavier elements. Everything heavier than boron was formed inside stars. Anything heavier than iron is extremely scarce in the Universe as a whole, and even iron is rare. The best reason that I know of for the concentration of heavy elements in the inner planets is that the solar wind blew most of the light materials like helium and molecular hydrogen away from the inner system while the planets were forming.
