Question: In what array simple cubic body centered cubic and face centered cubic
In what array (simple cubic, body-centered cubic, and face-centered cubic) do atoms pack most efficiently (greatest percent of space occupied by spheres)? Support your answer mathematically.
Answer to relevant QuestionsCalcium has a cubic closest packed structure as a solid. Assuming that calcium has an atomic radius of 197 pm, calculate the density of solid calcium. Barium has a body-centered cubic structure. If the atomic radius of barium is 222 pm, calculate the density of solid barium. What is an alloy? Explain the differences in structure between substitutional and interstitial alloys. Give an example of each type. Identify the most important types of interparticle forces present in the solids of each of the following substances. a. Ar b. HCl c. HF d. CaCl2 e. CH4 f. CO g. NaNO3 h. NH4Cl i. Teflon, CF3(CF2CF2)nCF3 j. polyethylene, ...Superalloys have been made of nickel and aluminum. The alloy owes its strength to the formation of an ordered phase, called the gamma-prime phase, in which Al atoms are at the corners of a cubic unit cell and Ni atoms are at ...
