Construct the Lewis structure for the covalent compound silicon dioxide (SiO2) using the following steps.
- The total number of valence electrons in SiO2 is ____.
- Arranging the atomic cores appropriately, write the Lewis structure for SiO2 in the box. Use electron pairs to show the bonds between the atoms. Distribute the remaining electrons so that each atom has an octet.
- If you have trouble placing all of the electrons, consider the possibility of using one or more double bonds in the structure. How many, if any, double bonds are required?_____.
