For fluorine it is 2 s 2, 2 p 5, for chlorine 3 s 2, 3 p 5 for bromine 4 s 2, 4 p 5, and for iodine it is 5 s 2, 5 p 5. In short, all the halogens have 7 electrons at the outermost quantum level or 5 electrons in the outermost p orbitals.
The valence electrons of an atom are those electrons that are in its outer energy shell or that are available for bonding. The American chemist Gilbert Newton Lewis (1875-1946) introduced a useful way to represent electrons in the valence shell of an atom. For elements in Groups IIIA through VIIIA the outermost s and p electrons in the highest energy shell are valence electrons. 2  For transition elements the valence electrons are those in the outermost s sub-shell and in the d sub-shell of the next to outermost energy shell.
