ClO2-,. Part D Determine the bond angle for H2CS. Although this may be confusing since there are different bonds, a double bond and a single bond is present, including triple bonds of the molecule, it still comes up with the same bond angles on all. On a (relatively) large scale these structures assume various forms: quartz chains, for example,. The bond angle Si-O-Si is nominally about 145 degrees, but can vary from about 100 to 170 degrees with very little change in bond energy. Now in the SiO2 molecule, you have to put the electron pairs between the silicon atom (Si) and oxygen atoms (O). The Silicon dioxide Lewis structure has a total of 16 valence electrons.
