2. You are tasked with identifying a piece of metal that has either a BCC or FCC structure. The following x-ray diffraction spectra using Cu-Ka radiation (0.1542 nm) corresponds to the metal. Use the information from the table in Problem 3 below to identify the metal. 100 Intensity (arbitrary units) 8 40H 60H 80 0 20 30 40 50 60 70 80 90 100 110 20 (degrees) 120 Atomic Radius Crystal Electronegativit Element (nm) Structure y Ni 0.1246 FCC 1.8 Valence +2 CHONOURNE 0.071 0.046 0.060 Ag 0.1445 FCC 1.4 +1 0.1431 FCC 1.5 +3 Co 0.1253 HCP 1.7 +2 Cr 0.1249 BCC 1.6 +3 Fe 0.1241 BCC 1.7 +2 Pt 0.1387 FCC 1.5 +2 Zn 0.1332 HCP 1.7 +2 2.
