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

Options

A. each silicon atom is surrounded by four oxygen atoms and each oxygen atom is bonded to two silicon atom
B. each silicon atom is surrounded by two oxygen atoms and each oxygen atom is bonded to two silicon atoms
C. silicon atom is bonded to two oxygen atoms.
D. there are double bonds between silicon and oxygen atoms

Answer

A

Explanation

Si is tetrahedrally surrounded by four O atoms. Each corner is shared with another tetrahedron, thus giving an infinite array: The difference between these structures is the way in which the tetrahedral `SiO_4` units are arranged.
