- At room temperature, crystal structures for cooper is of which type? Question 29 options: Body‑centered cubic (BCC) Hexagonal close‑packed (HCP) Hexagonal open‑packed (HOP) Face‑centered cubic (FCC)arrow_forwardThe spacing between two adjacent (123) planes in a simple cubic crystal with the lattice parameter a=0.4 nm is _______ (nm). Draw [322] in a body centered cubic crystal. Draw (202) in a face centered cubic crystal. The planar density of (003) should be higher than that of (002) in a body centered cubic crystal. Ture___ or False____. You need to justify why to the answer.arrow_forward3 Copper Unit Cell Uniqueness Here's a weird way to describe the structure of copper: Cu falls into the tetragonal crystal system with a = 0.256 nm, c = 0.362 nm = a√√2, and atoms located at 000 and. Its density is 8.94 g/cc at room temperature. (a) Draw a few adjacent units cells of the structure as described in this "weird" way. You should be able to see that there is a much more convenient way to describe the structure. What is it? (The point I wish to make is that there are many different unit cells that can be used to describe any given crystal, so we usually choose the one that is easiest to visualize.) (b) Calculate the radius of a copper atom using the above information. (c) Calculate the lattice parameter of the "better" unit cell of Cu.arrow_forward
