So this comes from Chapter two. Problem three of camp l asked. The reactivity of an Adam arises from a the average distance of the average of the outermost electron shell from the nucleus be the existence of unpaid electrons in the vale in shells sea, the sum of potential energies of all the electron shells or D, the potential energy of the violence shelves. So going to their chapter. What I'm sure you've realized is that the reaction's primarily occur in order to have a it's have stable failings, shelves and those valence shells. You. You want to have the outer most valence shell to be filled or to have no violence shows at all. So the average distance of the outermost electron shell from the nucleus isn't going to have a lot to do with what the Adam essentially wants, which is to have completed feeling shells. Of course, I'm anthropomorphizing Adams, but Adams or people Teo rate, so this really isn't going to have an impact on reactivity. The existence of unfair DH electrons in the Vaillant shells. Well, if a Vaillant shell has unfair DH electrons than, of course, it's going to want Teo react, it wants to fill those Vaillant shells once either have completed feeling shells or no shells at all. So be would be are correct. Answer some of the potential energies of all the electron shells. That's they're fine. Anatomy is fine if it's got high amounts of potential energies or low amounts of potential energies, so long as the veil shells are filled. So some of the potential energies of electron shells isn't goingto have nearly as much of an impact as the existence of unpaid electrons and the potential energy of the Valence shell again. Ah, it would prefer that the villain shall be complete rather than having any type of lower, high energy shell of the veil in shells. So what they're what on Adam really wants is to have complete valin shells or no violence shells at all. So again, our answer's going to be the existence of unpaid erred electrons and the Vaillant shells. Because on Adam is going to do what it has to do to ensure that it doesn't have any unpaid electrons in the failing shells, and to do that it will react. And thus the reactivity increases if there's unpaid electrons in the veil on Shell
