There are different electrons in the outer shell of each element.
Fluorine and Chlorine are in the 7th group. They have 7 electrons in outer shell.
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
All alkaline metals are very reactive. this is due to the number of electrons they have in there outer shell. they are situated in the group 1,2 and im not 100% group 6-7. this is because the group determines how many electrons are in the atoms outer shell. so with all atoms trying to get a full outer shell of electrons they will try and loose or gain electrons. so group one and two will quickly try and loose there 1 or 2 outer electrons to get a full outer shell thus making them very reactive and the same with group 6-7 they can not loose there electrons because this would make them positively charged and make it harder for electrons to leave so instead they gain electrons to achieve a full outer shell.
Group seven elements have 7 electrons in their outermost energy level.
They all have 6 in its outer shell because they are all in the same group in the periodic table. Your VERY VERY welcome (:

Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Valence electrons (electrons in the outer shell)
There are four electrons found on the outer shell of a atomic structure of tin. They are in a group of four.
7 electrons in total, 5 in the outer shell. Nitrogen is in group 15.

They have seven electrons in their outer shell they are in group seven on the periodic table.
It is a Group 2 element, therefore it has two outer-shell electrons. To gain a full outer-shell, it loses two electrons to form a cation (cations are positive ions)
