WebWhile both resonance structures are chemically identical, the negative charge is on a different oxygen in each. This is important because neither resonance structure actually exists, instead there is a hybrid. The oxygens share the negative charge with each other, stabilizing it, and reducing the charge on either atom. 2 comments. http://archive.sysbio.harvard.edu/CSB/research/oshea.html

WebDec 30, 2024 · These resonance structures show that the formal charges present on [PO4]3- atoms are not stationary, rather they keep moving from one position to another. Similarly, a double bond can be formed between the central phosphorus atom and any one terminal oxygen atom out of all the four available.
