Input (English): The Nozicki-Hiyama-Kishi reaction uses organometallic compounds featuring chromium or this element. It can be extracted from its oxide ore through heating in the presence of a mixture of hydrogen gas and carbon monoxide to yield a tetracarbonyl intermediate, which decomposes to yield four carbon monoxides in a process named for Mond. The diffraction pattern resulting from x rays fired at a crystal of this element provided evidence for the wave-particle duality in the Davisson-Germer experiment. A catalyst used to hydrogenate alkenes contains this element and aluminum, and is named for Raney. For 10 points, name this element with atomic symbol Ni.
Output (English): Science
