In this problem, we have kr, cl2.
00:06
So first if we will get how many balance electrons we have, crypto has 8, and each chlorine has 7.
00:13
So we get 22 electrons.
00:19
And if each chlorine gets an octet, that's 16 electrons.
00:26
So here, there's a 6 electron difference.
00:29
So that means three electron pairs will be on our central atom.
00:32
So we get something that looks like this.
00:41
And here, our molecular geometry is actually linear, which means this is non -polar.
00:51
But if we look at our electron domain geometry, we act as if each of our electron pairs is a bond.
01:06
So we can look at it like this.
01:15
So this geometry then corresponds with trigonal by pyramidal.
01:26
And if we look at formal charges, our corin is only the same...
