What are crystals?
A crystal is a solid where the atoms form a periodic arrangement. (Quasicrystals are an exception, see below.) Not all solids are crystals. For example, when liquid water starts freezing, the phase change begins with small ice crystals that grow until they fuse, forming a polycrystalline structure.

What is chemical reaction?
a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
