Crystal periodicity
For elements that are solid at standard temperature and pressure the table gives the crystalline structure of the most thermodynamically stable form(s) in those conditions. In all other cases the structure given is for the element at its melting point (H, He, N, O, F, Ne, Cl, Ar, Kr, Xe, and Rn are gases at STP; Br, Hg, and probably Cn and Fl are liquids at STP). Predictions are given for At, Fr, elements 100–113 and 118, which have not been produced in bulk. The latest predictions for …

WebNow, we've talked about long range crystallinity. We can have short range crystallinity. If I look at a ceramic, in this particular case, a glass, say quartz is O2, I can go from amorphous without form, meaning no long range periodicity, and I can also have crystalline ceramics, that demonstrate long-range crystallinity.
