Light elements like hydrogen and helium form a large percentage of the outer planets and Sun is made up primarily of hydrogen. Why are these elements nearly absent from the inner planets?
◦ The Sun captured all of the hydrogen during its formation.
◦ It is a mystery that has never been solved by science.
◦ Hydrogen and helium have all been bound up by chemical reactions on the inner planets and are held in rock.
◦ These light elements are blown away from the inner planets by the solar wind.
