Well since the electrons are always outside the nucleus and take part in bonding, the simplest way to find an element is by counting all of the electrons. For example, |dw:1377547071793:dw| By counting all the electrons (the x), we find out that there is a total of 8. Now, all the electrons on the the valence (or outer shell) can help determine the group number in which this element falls under. ok we have 6 electrons so it therefore means that this element belongs to group 6. Since there are 8 electrons, we then go to group 6 to search for that element. From there, we find that Oxygen has 8 electrons. You :can see this at the top left hand corner. |dw:1377547389577:dw| In concluding the element that has 8 electrons and is in group 6 Is OXYGEN. NOTE: If an electronic configuration is given you don't have to draw the diagram, fill it up and count. you just simply add the numbers in the configuration for example, 2.6 ....this means that there are 2 electrons in the inner shell and 6 in outer shell making it a total of 8 electrons. Hope this Helped ! ^_^

|dw:1377575015393:dw| A = molecular weight = neutrons + protons B = # of proton, which is equal to electrons in a uncharged state/non-ion C = Proton minus electrons (will tell you the charge on the ion)
