Question

Consider the molecular orbitals of the P2 molecule. Assume
that the MOs of diatomics from the third row of the periodic
table are analogous to those from the second row. (a) Which
valence atomic orbitals of P are used to construct the MOs of
P2?

Hello everyone. So in this video we're going to talk about the dye atomics in the third period of pr table. And we're going to assume that it has some similar molecular orbital as the dye tonics from our second period. So let's go ahead and kind of draw out the molecular orbital um diagrams. So for our di atomic molecular orbital diagrams for age two all the way through. And to that's going to be of course our first one is sigma to P start. Then we have our Pie two P. Start. Then we have are sigma two people than our Pie two. Then our sigma to us start and just scroll down just a little bit. And then last line is going to be our sigma to us now for our die atomics of 02 To NA two have again our sigma two P. Star. Then we'll have our pie two P. Start and this one is a little bit different. We have our pie two people then our sigma two P are sigma to us start and lastly are sigma to us. And of course When we're talking about the 3rd period Then we'll have our three S and three p. Instead of r. n. p. and two s. So those are gonna be For a period three elements. All right, so the veils electron configuration of our sulfur. That's what we're talking about here. It's going to be and E three S two & three p. 4. So you see this enemy here it's going to be talk about this any here. So the inner overdoes aren't involved in bonding and the molecular um the molecular orbital's that formation is only going to concern our fans, electrons and that's why we wrote out the vans electric configuration of this, which is right over here. So in that case then let's throw down again just a little bit for our sigma three S and our sigma star three S. That's great to talk about of course our three S orbital and then for our sigma three P, our sigma star, repeat Our Pi three p. And of course, lastly, our pi star repeat the concerns, all of our three p orbital's alright scrolling down again. And just because we have everything out here then our final answer again, let's go back and re read our question bring To determine the balance atomic orbital of S used form the molecular orbital of the S- two atomic. So from this list here then We'll have our three three peat, sub X three piece of wine and three piece of see. And that is going to be our final answer. But that's a problem
