2 – Crystal Structure

crystalline solid – the atoms or ions arrange in a pattern that repeats itself in three dimensions to form a solid which has long-range order amorphous solid – materials with only short-range order space lattice – a network composed of an infinite three-dimensional array of points unit cell – the repeating unit in a space lattice lattice constants lattice vector – a, b, c interaxial angle – α, β, γ
