As rocket fuel, the metastable metallic form of this element would produce a specific impulse 3 times greater than the Space Shuttle main engine. The fuel hydrazine features four atoms of this element surrounding a pair of (*) nitrogen atoms, and the external tank of a Space Shuttle held liquid forms of oxygen and this diatomic gas. The most abundant element in the universe is, for 10 points, what element with atomic number 1 and atomic symbol H?
