 Okay, so let's try this one now. It's, again, the relative size of particle question, but this time we're talking about the ion relative to its parent atom. So in this case we've got cation from its parent atom, and here we've got an anion being formed from its parent atom. So remember what we just discussed. When you've got a nuclear charge that's greater than your electronic charge, of course the nucleus is going to have a higher, a stronger effect on the electron cloud than it would if the charges were equal. So in other words, right, we've lost some electrons, so the nucleus has a much stronger pull on the remaining electron. So in that case what you'll find is that the particle size of the cation is significantly smaller, especially when you go to the 2 plus, go to 3 plus is really good smaller, significantly smaller than its parent atom. So which one of these is, I can't remember the question, larger or smaller? Let's just do smaller. Okay, so which one of these is smaller? It would be the beryllium 2 plus cation. And again the opposite argument is not true for anions, right? So charge, so it's more diffuse because the nucleus doesn't have as much an effect on, as much pull, so it actually gets more diffuse, so the parent atom is going to be smaller. This is a general trend that you'll see.
