In silicon dioxide:

  1. A
    Each silicon atom is surrounded by four oxygen atoms and each oxygen atom is bonded to two silicon atoms
  2. B
    Each silicon atom is surrounded by two oxygen atoms and each oxygen atom is bonded to two silicon atoms
  3. C
    Silicon atoms is bonded to two oxygen atoms
  4. D
    There are double bonds between silicon and oxygen atoms

Solution & Step-by-step Explanation

does not exist as discrete molecules. It is a covalent network solid.Each Silicon atom is tetrahedrally coordinated to four Oxygen atoms.Each Oxygen atom is shared between two Silicon atoms.This forms a continuous 3D giant macromolecular structure.
