Hello everyone in this video we have to go ahead and draw the LewiS structure for this compound here. As well as drawing the resident structures if it's necessary. So we have to go ahead and recognize that the compound is composed of the A. L. Three plus carry on as well as the P minus an ion. So for our car and then we can go ahead and leave it off to the side here. But for our poly atomic and I only have to go ahead and actually calculate the band's electrons before I could go ahead and actually draw the structure. So we have our phosphorus atom as well as the oxygen atom. So phosphorus in group five A. So there's going to be five bands electrons. As for oxygen atom is in group 68. So there's going to be six valence electrons in this molecule here. We have a total of four bands electrons but four oxygen atoms. So six times four is 24. And these two numbers up, we get total of 29 vans electrons. So we have our phosphorous atom being the most or the least electro negative. So I can go ahead and be the central atom And of course we have connected to four oxygen's. So usually oxygen does like to have a double bond to go ahead and put that there. As for the other three auction atoms it cannot have a double bond or else is going to break this architect role of the sexual item. So let's leave it as a single bond and just add three long pairs to each atom. In that case we'll have a -3 formal church because one coming from each of the single bonded oxygen's alright for our resonance structures. The double bond can be between philosophers and any of the auction Adams. So we're gonna go ahead and create a total of three other as instructors because we're just alternating that pi bond. So again having this double arrow, then the corona stays on the outside. The only thing changing is rotating our double bonds. So we have that double bond oxygen on the left side here with one of the resonance structures. Again we have to go and add our long piers With our 3 - Charge. Next one go ahead and have the double bond on the lower oxygen. Again. Our aluminum can can be on the outside so we have the P. M. Central atom on the bottom and single bond for the rest Of course they'll have a 3 -6. And lastly we can go ahead and have the pipe on be on the right again, the aluminum can on the outside to give us a little bit of space. So we said now that the taliban is going to be over to the right oxygen, the same exact thing. Three long pairs for the single bonded oxygen and two long pairs for the double bonded oxygen First The 3 - Charge. So then these four shifters here all can be our little structure but all together will be the resonant structures for the a l p o Floor Combat. Thank you all so much for watching.
