Suppose you synthesized copper nanoparticles and found the average particle diameter to be 6.2 nm.How many copper atoms would you expect to find in the particle?One approach: assume the particle is spherical. In all cases, assume the particle has 24 Cu atoms across the diameter (the radius of each Cu atom is 128 pm)What fraction of the atoms would be surface atoms.
