1) Calculate the percentage of empty space in a simple, body-centered, and face-centered cubic unit cell using geometry and algebra without substituting any values for atomic radius (r) or cell length (a). The volume of a sphere is 4πr3 3 Hint: Express "a" as a function of "r." The variable "r" will cancel out when you calculate the volume of "atoms" in the cell to give a number which is the fraction of occupied space. The rest of the space is empty.

Nanotechnology, or technology utilizing 1100 nm sized particles, has rapidly expanded in the past few decades, with potential applications ranging across far-reaching fields such as electronics, medicine, biomaterials, and consumer products, to name a few. One of the primary advantages of nanoparticles is the presence of large surface/mass ratios, resulting in enhanced surface activities compared to bulk materials. a Use the density of silver (10.49 g/cm3) to determine the number of Ag atoms in a spherical 20.-nm silver particle. b In the crystalline metallic environment, the measured radii of silver atoms has been measured to be 144 pm. Use this to calculate the atomic packing fraction of a 20.-nm silver particle. In other words, calculate the ratio of the volume taken up by Ag atoms to the volume of the entire nanoparticle. c Based on the result of part (b), silver conforms to which type of cubic crystal lattice? A simple cubic B body-centered cubic C face-centered cubic d A cubic Ag ingot having a mass of 5.0-g is processed to form a batch of 20.-nm Ag nanoparticles.
