what electron arrangements are stable
full outer shells are...
full electron outer shells don't ____ _____ and don't need to _____ with anybody.
form bonds, react with anybody
what group are noble gasses on the periodic table?
atoms want to be like _____ ______ which are stable with full outer __ and ___ shells.
noble gasses, S and P
what is the magic number?
8. s^2 + p^6 = 8
what element is stable with just 2 electrons not 8?
______ _____ give, take or share electrons to obtain what?
representative electrons, to obtain noble gas configuration
why do we draw boars models with 2,8,8,8?
because of noble gases, after their first shell they want 8 to become stable
what are representative elements?
everything on the periodic table except the Bs

full or half full, more stable
one unpaired electron makes it ___ stable than if its _____ shell had no unpaired electrons
less, no unpaired electrons
