Web2 days ago · Step 1: Count the total number of valence electrons in SiO2. The first step is to determine how many valence electrons SiO2 has. Since silicon is in the 14th group of the periodic table and oxygen is in the 16th group, silicon has a 4 valence electron and oxygen has 6. Oxygen’s electronic configuration = 1s2 2s2 2p4. WebWhy is silicon dioxide considered a covalent network whilst carbon dioxide is considered a molecule? Carbon and oxygen are about the same size atoms. As a result, there is good overlap of the orbitals, especially the unhybridized p orbitals on C with a P on O to form a C=O double bond.
