In the lewis dot structure for sio2, how many total valence electrons are there in the entire molecule, including the ones used to form bonds?

Explanation:

The total valence electrons present in molecule are as follows.

         Valency of Si + (Valency of oxygen × number of oxygen atoms)

          = 4 + (6 × 2)

          = 4 + 12

          = 16

Therefore, there are total 16 valence electrons in molecule including the ones used to form bonds.
