Now, fluorine has nine protons and nine electrons. So once again, our nucleus will have nine protons, and our mutual fluorine atom will have nine electrons floating around the nucleus. So once again, let's apply our octave rule and let's see how many electrons this fluorine atom, this neutral fluorine atom needs to gain to obtain a noble gas configuration. 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.
