In silica (SiO_(2)) each silicon is bonded to :

In silica (SiO_(2)) each silicon is bonded to :

In SiO_(2) , each silicon atom is surrounded by

In silicon dioxide : each siliçon atom is surrunded by four oxygen atoms and each oxygen atoms is bonded to two silicon atoms, silicon atom is bonded to two oxygen atoms , there are double bond between silica and oxygen atoms, silicon atom is bonded to five oxygen atoms

(A): The hardness of silica is less than that of diamond . (R): In silica, each silicon atom is surrounded by two oxygen atoms whereas in diamond each carbon atom is surrounded by 4 carbon atoms
