So this single hour electron will not experience as much charge as it would if these guys weren't here. Now, let's compare this guy. Notice that in this guy we have one more electron in our outer shell. And what that basically means is that because our ratio of eight to outer is smaller, that means this shielding effect will not be as great, because now we have an extra electron floating around our shell. So these guys will experience more charge than Dixon electron on the lithium. And what that means is that these two electrons will be pulled closer to the nucleus than here.
