Lewis structure of so3

Sulfur brings 6, and oxygen brings 3 each. That means; SO3 has 24 valence electrons. 6 + (3 x 6) = 24. When we draw it, firstly we get the three structures at the top.

Explanation:

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
