Question

Consider the H2+ ion. (a) Sketch the molecular orbitals of 
the ion and draw its energy-level diagram.

Accepted Answer

Hello everyone. So in this video we want to go ahead and draw the molecular orbital is formed and also write the molecular orbital energy diagram for this ion right over here. Alright, so let's get started. What we need to do first is, well there's actually two steps that we need to do. First step is to go ahead and calculate the total number of valence electrons that are present. So we have our helium Element, that's a group to eight. So there's going to be two vans electrons per atom because we see in our molecule here that there's two atoms of helium, we can go ahead and multiply by two to give a total of four valence electrons. So again, of course we have this plus charge here. This plus one charge. We can go ahead and add or lose one electron. So we also go ahead and subtract one electron that gives us a total for this ion then to have three valence electrons. So using this information, we'll go ahead and use that to go ahead and fill out our molecular orbital energy diagram. So I can maybe have guests that Our second step is to go ahead and draw the molecular orbital diagram. So let's go ahead and do something So far. HE two plus the molecular herbal diagram started off with our sigma and then our sigma start. So we have again these three advanced electrons and using Hunt's rule going from bottom to top. Let's go ahead and fill it out. So we have 12 and three. So that's going to be how simple it is by first calculate the total number of vans electrons, then writing out our molecular orbital diagram and filling out those electrons. Alright, so then our answer for this is going to be right over here. This molecular orbital diagram. All right, thank you all so much for watching. Hopefully this helped.
