Question

For each of the following silcate mineral, indicate whether it is made up of individual orthosilcate anions (a "zero-dimensional" array), linear chains having Si-O-Si-O- linkages (a one-dimensional array), layers made up of alternating -Si-O units (a two-dimensional array), or a lattice in which the silicon atoms are connected by oxygen bridges in three dimensions.

(Write 0,1,2, or 3 to indicate which structure would be adopted).
