It is made up of a continuous framework of SiO4 silicon-oxygen tetraheda, with each oxygen being shared between two tetrahedra, giving an overall formula SiO2.
Atamku wuxuu ku xiran yahay qaab si isdaba joog ah u ah SiO4 silsilad oxygen tetrahedra, iyadoo oksijiin kasta la wadaago inta u dhexeysa laba tetrahedra, isaga oo siinaya qaaciddada kiimikada guud ee SiO2.
