elements fine large it's not possible to form compounds with him well it's a shame for the noble gases where does that term noble gases come from where they how do you build a today rescue maidens now you're thinking of Heroes there like nobility in the sense that they don't mix with the Riff Raff they don't like to react with any other find large it's not possible to form compounds with both of Shame for your collection that their gas is because you got big blanks here the noble gases like neon and argon pose a problem for chemists who prefer their elements to join forces and react with each other you can run an electric current through them excite their electrons and get pretty colors which is how neon lights work but the noble gases don't react he pretty much refused combine with other elements being an inert gas being unwilling to mix with the other elements react with them this is a very clear-cut distinction start this particular column from all the others in the periodic table so why are these guys so aloof  is it turns out protons maybe Germany 50 of an element's electrons reactivity  and reactivity is a shell game here's how the game is played imagine these balls are electrons and the target is an atom  electrons don't just pile on around the nucleus Skee-Ball where you land Rosa jetsetter house  electrons take up positions in what can be thought of as Concentra the first shell Max is out it just two electrons the next holds 8 then it goes up to 18 and Adam electrons in its outer shell makes one happy satisfied atom and noble gases come equipped with completely satisfied shells is this the only common like that is the only problem we're all the shells are completely filled but what about the column just before those stable noble gas they're called the halogens they have an outer shell that needs just one more electron to be full and I'll grab it anyway they can the group includes fluorine and bromine but the most notorious  is chlorine protons surrounded by 7 electrons arranged in three shells of two eight and seven one short of being fault if that extra electron will get any way it can sometimes with violin results  that's why chlorine gas was used as a deadly poison in World War I chlorine I mean this is nasty stuff this will take electrons from kittens you know it'll it'll go and steal an electron off the water in your lungs turn it to hydrochloric acid because it really wants an electron yeah maybe I'll leave it where it was not if you end up with the alkali metals the alkali metals are the First Column YouTube them has full shells plus one extra electron sitting in a new outer shell steal your names like sodium and potassium and they all want to get rid of that single lonely electron anyway they can
