Calculate the radius of copper atom. The atomic weight of copper is 63.55 g mol-1. It crystallises in face centered cubic lattice and has density of 8.93 g cm-3 at 298K. (NA = 6.023×10^23 mol-1)
An alloy of gold (Au) and cadmium (Cd) crystallises with a cubic structure in which gold atoms occupy the corners and cadmium atoms fit into the face centres. What is the formula of this alloy?
