And so it does not require a lot of energy change to add an electron onto the element. And so the likelihood of the protons wanting to attract another electron, um, is very low. And this is mainly because, as you go down a group, you have elements that have more and more electrons occupy higher energy levels. And once you go down a group, typically the electron affinity, we'll decrease.
And so if we add another electron to make those tp six, this would actually achieve the noble gas configuration which is very stable And so that's one way Thio understand why the electron affinity increases from a lot too right for a period.
#Electron affinity tv
And so, for example, if we have something like Maureen, Chlorine has an electron configuration of one s two Tosto and TV five. And so this makes ah lot of sense merely because as you go from the left to the right, these atoms will want more electrons to achieve the noble gas configuration. And so if we add an electron, this ends up making a kind of and so generally when we talk about the electron affinity in terms of the periodic trends, um, typically, when you go from the left to the right or across a period, the electron affinity increases. And so this can be demonstrated by a solar example from four.
And so electron affinity can be thought of as the opposite of the ionization energy in the sense that for electron affinity, this is the energy change as a result of the addition of an electron thio.
We learned about the ionization energy, which is essentially the energy that is required to move to remove an electron from Adam.
