WebMay 1, 2024 · Interplanar distance in FCC and BCC. d h k l = a h 2 + k 2 + l 2. This source says that the interplanar spacing of the ( 111) plane in FCC is a 3, which is in agreement with the formula above. However for BCC, interplanar spacing of ( 111) is said to be a 2 3, which doesn't agree with the formula. WebChromium is a chemical element with the symbol Cr and atomic number 24.
