Covalent Nature of SO3 Compounds

The video explores whether sulfur trioxide (SO3) is ionic or covalent. By examining the periodic table, it is determined that both sulfur and oxygen are non-metals, indicating a covalent bond. The structure of SO3 shows double covalent bonds, where electrons are shared between sulfur and oxygen. The small electronegativity difference between sulfur and oxygen supports this covalent nature. Dr. B concludes that SO3 is a covalent compound.
