So since nine is very close to ten, so this fluorine has nine electrons, which is only one away, one less than neon, that means fluorine will tend to gain an electron to form our neon noble gas configuration. So, once again, if we have an electron floating around this fluorine nucleus, it will tend to take that electron and place it into one of the two p orbitals so that once it places it there, it has a noble gas configuration. So, once again, this neutral fluorine atom gains one electron, puts it into the two p orbital, and it becomes an electron configuration that matches that of neon. So it has two electrons in the one s. It has two electrons in the two s and six electrons in the two p. Now, this guy is very happy because he's very stable, and that's because noble gases have very stable electron configuration. And that's basically what the Octave Rule is. It's basically a procedure, a process that you follow that will give you a noble gas electron configuration.
