1.(a) Define what are Crystalline Solids and Amorphous Solids? (b) Explain, with a two-dimensional representation, the amorphous and crystalline forms of SiO2? (c) The density of matter largely depends on the atomic weight of the atoms and how closely packed they are in the crystal structure. The atomic weight of nickel is 58.70 amu, and it has a face-centred cubic structure, with a lattice parameter of 3.52 Å. Estimate the theoretical density of nickel.
