Below are listed diffraction angles for the first three peaks (first-order) of the xray diffraction pattern for some metal. Monochromatic x-radiation having a wavelength of 0.1254 nm was used. i. Determine whether this metal's crystal structure is FCC, BCC, or neither FCC or BCC and explain the reason for your choice. ii. If the crystal structure is either BCC or FCC, determine the atomic radius of the metal. Peak Number Diffraction Angle (2 q) 1 31.2° 2 44.6° 3 55.4°
