Okay, so here we want to rank these bonds in order of polarity.
00:04
So the way that we are going to compare these is each of these are bound to a fluorine, and what determines polarity is how different the two atoms are in a bond.
00:15
And so if you look at the periodic table, a good rule of thumb is that the further away different atoms are in the bond, based on their position in the periodic table, the more polar that bond is going to be.
00:27
So if we think about it, nitrogen and fluorine are both on the right side of the periodic table.
00:33
They're both nonmetals.
00:35
And they're both relatively high on the electronegativity scale.
00:41
So these are pretty similar when we're comparing positions on the periodic table.
00:49
If we think about lithium and fluorine, lithium is on the left side of the periodic table, and it's in the far left column.
00:57
So it is very different from fluorine.
01:00
It is not very electronegative.
01:02
In fact, it usually would have a positive charge of anything.
01:05
So these are very different...
