Framework silicates have the most sharing of corner oxygen atoms because each tetrahedron shares all of its oxygen atoms with adjacent tetrahedra, creating a 3D network. Single chain and double chain silicates have less sharing of oxygen atoms because the chains only share some of their oxygen atoms, while sheet silicates have even less sharing because they only share one plane of oxygen atoms.
