Most red giants will eventually fuse into a core of this element before going supernova.
Most red giants will eventually fuse into a core of this element before going supernova. Every radioactive element with a mass above that of this element will eventually decay primarily into it, although it is possible to fuse isotopes of elements heavier than it into metastable nucleides. When it is neutrally charged, it has an unfilled d shell, and often has a charge of +2 or +3. A lack of this element in blood causes anemia. For 10 points, name this most stable element in the universe, whose ions are often called ferrous or ferric.
