Question

In silicon dioxide :

• A. Each silicon atom is surrounded by four oxygen atoms and each oxygen atom is bonded to two silicon atoms
• 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 1

Answer: (A)

Silica is another name for the chemical compound composed of silicon and oxygen with the chemical formula $Si{O}_2$ . In this silicon atom shows tetrahedral coordination, with four oxygen atoms surrounding a central silicon atom and each oxygen atom to two silicon atoms. It forms three dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to four oxygen atoms.
