WebMay 20, 2024 · Ionic crystals - The ionic crystal structure consists of alternating positively-charged cations and negatively-charged anions (see figure below).The ions may either be monatomic or polyatomic. Generally, ionic crystals form from a combination of Group 1 or 2 metals and Group 16 or 17 nonmetals or nonmetallic polyatomic ions. 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, … See more Close packed metal structures Many metals adopt close packed structures i.e. hexagonal close packed and face-centred cubic structures (cubic close packed).
