Okay, so i have listed a few bands here in front of us, and we want to look at each side as a partial positive or partial negative.
00:12
So in order to do that, we're going to be looking at electronegativities.
00:16
When more electronegative atom will be able to attract electrons more, which means that side is going to have the partial negative.
00:27
So if we take a look at this first one, nitrogen and fluorine.
00:32
We want to remind ourselves of the electronegativity trend, and that increases across a column, and it also increases going up the group.
00:42
And so, like, fluorine is the most electronegative atom.
00:48
So, coming back to nitrogen and fluorine, fluorine we already said, was more electronegative than nitrogen.
00:54
So fluorine is going to have the partial negative.
00:57
Nitrogen will have the partial positive.
01:02
Okay, now silicon and bromine...
