Step 1: Draw the Lewis structure of silicon dioxide (SiO₂)
Silicon dioxide, SiO₂, has a total of 16 valence electrons (4 from Si and 6 from each of the two O atoms). To draw the Lewis structure, follow these steps:
Step 2
Place the central atom, silicon (Si), in the middle.
Final Answer
Distribute the remaining valence electrons to complete the octets for each atom. The Lewis structure of SiO₂ is: ``` O := Si := O
