I don't get this AT ALL !! please help.I can't find anything in my chembook that helps so this is my last resort ! :|the intrustions say the following:List the charge of the ion most likely to be formed from the element and the name of the noble gas with an electron configuration achieved by that formation(The atomic of the noble gases are: He,2Ne, 10Ar, 18Kr,36Xe, 54and Rn,86.)1Lithium (atomic 3)2Oxygen (atomic 8)3Sulfur (atomic 16)4Aluminium (atomic 13)thanks to anyone who'd bother lol
Yeah the instructions did seem a bit confusing1Lithium has 3 electrons because it has a proton number of 33 is closest to the number 2 which is the electron and proton number of HeliumTherefore, to get down to 2, it would LOSE an electron, and therefore become a +1 charge because it has one more proton than it does electrons2Same thingOxygen has 8 electrons because it has a proton number of 88 is closest to the number 10, which is the atomic number of NeonTherefore, to GAIN up to 10, it would GAIN 2 electrons, thus becoming a -2 charge because now it has 2 more electrons than it does protons3Sulfur's proton and electron number of 16 is closest to the number 18 which is the atomic number of ArgonIt needs 2 more electronsSo it gains 2 electons and has a charge of -2 because it has 2 extra electrons than it does protons4Aluminums's proton and electron number of 13 is closest to the 10 which is the atomic number of NeonIt needs to LOSE electrons, so it will lose electrons, and will therefore have a +3 charge because it now has 3 more protons than it does electrons (or 3 less electrons than it does protons)I hope that wasn't too redundantI just wanted to make sure you understood how I got my answers.
Ask at your local hardware store or search the yellow pages for construction suppliers.
