So to draw the lewis structure of clf3, first we're going to add up all valence electrons that we have available to us.
00:09
So in clf3, each chlorine has seven valence electrons, and each fluorine also has seven.
00:18
So we need seven times three plus seven, and we get a total of 28 electrons that we can use.
00:26
So to draw up the lewis structure, chlorine is our central atom bonded to three fluorines.
00:45
And so that's used up six of our 28 electrons.
00:48
And now we can complete the octet of each of the fluorines.
00:55
And now we still have four electrons left.
00:57
So we're going to add those to our chlorine.
01:05
So this is the lewis structure of clf3...
