But what’s happening here? So I can go ahead and put a hydrogen in here and a hydrogen in here, and connect the dots. So if I look at the molecular formula CH4, which is methane, and I want to draw a dot structure for the methane molecule, Oribtali would go over here to my organic periodic table and find carbon.
Maybe I’ll make another video on that. So I’ll do that in a second.
This is a sigma bond, sigma bond, and then we have this hydrogen in the back, which is also going to form a sigma bond. So let’s go ahead and count them. Now when you’re drawing dot structures, you don’t always have to do this step where you’re drawing each individual atom and summing all of your valence electrons that way.

Wzory elektronowe kropkowe II: So it’s a pure p orbital that’s kind of going in, maybe you can imagine, the z-axis, that the other orbitals are kind of a Mercedes sign in the x, y plane.

So if I look at the second period, I can see that the valence electrons for carbon would be one, two, three, and four. So let me draw what it would look like, or our best visual, or our best ability to kind of conceptualize what the orbitals around the carbon might look like.
Your 2s orbital only mixes with one of the p’s, so these are sp hybrid orbitals forming sigma bonds, so all of these right here. Now I can see that carbon is surrounded by eight electrons here.
Transkrypcja filmu video In the last video, I touched on the idea of a sigma bond. And I can see there’s a place for them on the nitrogen. So let me draw the nucleus of two atoms, and I’ll just draw one of each of their p orbitals. They’re actually sp hybridized. So if I look at the molecular formula CH3 NH2, I’m going to once again start with carbon in the center with its four valence electrons around it, like that.
Therefore, hydrogen will have one valence electron. So here, our two p orbitals are parallel to each other. So he has this bond right here, which would be an sp2 hybridized bond, just like that. And then this guy has an sp3 hybridized orbital as well. We have a double bond here. And if you’re curious, when you’re dealing with– just to kind of make it clear, if we were dealing with ethyne, this is an example of ethene, but ethyne looks like this.
Let’s do one with oxygen next.
Now sigma bonds, which are what form when you have a single bond, these are stronger than pi bonds; pi bonds come into play once you start forming double orbitzli triple bonds on top of a sigma bond.
The spatial arrangement of these orbitals is tetrahedral. I, the copyright holder of this work, release this work into the public domain. They’re pointing at each other. So oxygen is going to follow the octet rule. The following other wikis use this file: They overlap in kind of the direction that they’re pointing in. And so that s orbital holds a maximum of two electrons. And so if I find hydrogen here, hydrogen is in the first energy level.

So everything I’ve drawn so far is hybrtdyzacja sigma bond, so that, that. This hydrogen is kind of in the plane of the page, and then maybe that hydrogen is behind it, and then you have one hydrogen popping up.
It comes out like that. To double check yourself, you could make sure that your dot structure has the correct number of valence electrons.
