Best Answer

Iron and Nickel

Answer

the core must be iron metal along with some nickel. But it's less dense than pure iron, so about 10 percent of the core must be something lighter. Sulfur and oxygen are the two best candidates, though hydrogen has also been considered. But the money is still on one of the other two, with oxygen looking slightly more probable, or maybe both.
