Need some help understanding oxidation values I am needing to better understand the oxidation numbers assigned to compounds. On one hand, the oxidation number of a neutral compound is 0, such as H2O. But, then I have another rule in my notes that states "In a binary compound, the oxidation number is equal to the charge of the element with the greatest electronegativity", an example being PCl3, which has an oxidation number of -1. So how do I make sense...
