So, what would the charge be of aluminium when it LOSES or GAINS electrons to become more stable and please show how you did thatExHow would you find out how much the element would lose or gain to become more stable and how you would find the new chargeAlso, please show why you did each stepThanks a ton! Also: When you are finding how many electron an atom would lose or gain to get a full outer level would you take into consideration the full amount of electrons in the energy level or would you just look at the electron configuration pattern and find out how many electrons there would be in that energy level until it jumped to another? (EX3s^2 3p^6 4s^2: it would be jumping from the 3rd energy level to the 4th energy level inbetween 3p^6 and 4s^2)The charge on an individual electron is −1.6022 ×10^−19 C [1]This is a discrete charge so adding an electron reduces the overall charge by 1.6022 ×10^−19 C and removing an electron increases the charge by that amountAtoms, before addition or removal of electrons, have zero net charge, although there is a distribution of that charge between the nucleus and the electron shellsTechnically this answers your primary question, however I suspect you are really asking a broader question When forming ions, electrons are added or removed from the outer shell to form a stable configurationFor row 1 or row 2 elements in the periodic table, the octet rule [2] will helpElements with only a few outer shell electrons will find it easier to lose those electrons, whereas elements with almost complete outer shells will find it easier to accept electronsThe number of electrons added or removed will determine the charge by increasing or reducing the charge by -1.6022 ×10^−19 C for each electronIn your example of aluminium you have an electron configuration of (Ne) 3s2 3p1Because there are only a few outer shell electrons this would tend to lose electronsTypically aluminium would form ions by removal of between one and three electronsThis can be seen in the oxidation states of 1, 2 and 3 for aluminium [3]Other states are possible, they\'re just not energetically favoured Removal of electrons when forming an ion is a wholesale thingThis isn\'t jumping from one energy level to another, but a complete removal from the electron shellsExcitation (moving an electron from a lower to a higher energy level) does not create an ion (unless the energy is sufficient for dissociation) and when the excitation source is removed the energy levels are restored and the excess energy emitted in the form of lightYou\'ve really touched on a lot of topics hereI\'ve tried to cover most of theseHopefully there\'s enough here to help a littleEnjoy  Other related question

| Baking a pie in an oven with cast iron stove top pan |

I know it\'s recommended by instructions to use a cookie sheet while baking a frozen pie in the ovenBut, if I don\'t have one, is using a cast iron stove top pan safe to use? Or will it drastically affect the temperature the pie is being heated, etc?The cast iron might get too hot and effect the heat the pie cooks at, but at least your bottom crust should be nice and crispNext time, just put down a sheet of aluminum foilThat cookie sheet is just to protect your oven in case the pie filling spills over and to make handling the hot pie easier to remove from the oven If the pie looks like it is cooking too fast, cover the edges with foil to keep them from browning too fastNote: If possible, cover the cast iron top with foil to avoid spill overs on thatMerry Christmas.Other related question

which is the best, cling wrap, aluminium or grease paper.or shud u just leave the food without a wrap.[this is talking about a cheese sandwich] then which one doesnt mould quickerThe bread will dry out pretty quickly if you leave the sandwich unwrappedWhether you use aluminum foil or cling wrap, the cheese will mold in the same length of timeCling wrap will keep it from getting stale and dry longer than aluminum foilBut, a plastic zipper sandwich size bag would work better, if you have one.Other related question

I know about the cardboard tube filled with hay but my rabbit seems to grab it with its teeth and throw it and just sits there does that mean he likes it? and are there and toys i can Make and insructions on hot to make it? thanksbyeThe cardboard tubes are a good start, here are a few other things you can get that are quite cheap or nearly freeA cleaned aluminum soda can with the pull tab removedThey pick it up, toss it, push it around, etcThe hard plastic cat toy balls, especially with the bells inside but not the flimsy ones where the bells can be easily dislodgedAgain, they\'ll toss them, carry them, push them aroundA small length of plastic or nylon chain that can be picked up at Home Depot, Lowes, etcCut the chain so that it hangs down level with the rabbits\' headThey will chew on it, knock it around, stand up to chew on the upper links, etcAnd of course, don\'t forget a wood chew stick to them to chew on and keep their teeth in proper orderSome people use natural woods approved for bunny use but I like to pick up the 2x2 size wood at Home Depot and cut it into about a six inch lengthNot only will they chew on it and keep their teeth sharp and trimmed, they\'ll also pick it up and carry it or toss it aroundHave fun with your bunny!

So I was trying a home chemistry experiment with sodium hydroxide and aluminum foilI put a bit of sodium hydroxide in a cup, mixed it with water, and reacted some aluminum foil in itIt left a black residue (which I believe to be carbon from the coating on the foil)I left the cup on the windowsill and when I came back a few days later, the black precipitate was orangeThe cup was glass, if that would mean anythingI know that sodium hydroxide can dissolve that sometimes.the black precipitate probably oxidized by sitting in the sun and in the open air2 [Al(OH)4]1- (aluminate ion) forms when Al is placed in NaOH if allowed to sit long enough, the Al(OH)4-1 ion may form with the Na+ in solution to make NaAl(OH)4 as the liquid evaporates.Other related question

I need to unroll a bunch of aluminium foil and then reroll it in smaller packageshow can i get it to stay straight on the tube as i\'m rolling it back up? whenever I try- it veers off course and I can\'t keep it straightis there something i could build or a way to keep it straight?The biggest key to rolling it straight this that you start it straightjust because you cut it straight does not mean it is straightThere is noway that I know of except trial and error to do thisWe have laminaters at work that we do this with but the same applies it all depends on starting the rollThe bigger diameter core you use to start with the easier it is to adjustGood luckOther related question

AlrightI have a few things I need to do, and I\'m not sure how to go about doing themthat\'s why I\'m here! Your help would be appreciated :]First thing I\'m supposed to do is figure out whether the following list is in order of increasing or decreasing ionic radiusHow would I know? If you could tell me how that\'d be great :]Here it is:7N^3- 8O^2- 9F^- 11Na^+ 12Mg^2+ 13Al^3+And I\'m also supposed to figure out the number of electrons in each of the ions aboveHow do I do that? Chemistry is not my forteeheh ~_~Best answer to whomever :]the more shells the wider the radiusso first write out the electronic configuration for each so that is : nitrogen - 2:5.7 electrons .oxygen - 2:6.8 electrons sodium 2:8:1.11 electronsmagnesium - 2:8:2.12 electrons aluminium - 2:8:3.13 electronsin the order of smallest radius to largest radius is: nitrogen ,oxygen,sodium,magnesium,aluminiumOther related question

using those typical 8- 9 inch aluminum foil cake pans you can find at the average dollar store for a dollar maybe do they tend to not bake the best round cakes when making a layer cakei wondered if using a real aluminum cake pan would bake a more even and well baked cake?The metal is too thin to spread the heat around.It will often be soggy and burnt at the same time.Try to find either stainless steel or heavy gauge aluminum.I get nervous using dull aluminum pans as they might leach metal into the food and kill your brain cells.The iron in the stainless steel resists this and if it does,your body uses it to make blood cells anyway.Other related question

Where do you draw the line between accepting the threat terrorism poses to the world and fear-mongering?The line gets crossed when an administration invents lies to add to the fearSuch as using forged uranium documents, spreading false stories of nations having close ties to Al-Q, telling falsehoods about mobile chemical labs, and lying to the nation about the use of aluminum tubes to enrich uraniumAs long as you tell the truth you are not fear mongering.Other related question

Can you accomplish air conditioning by pushing air through a tube surrounded by water? I\'m attempting to use water as a sort of heat sink.pushing air through a highly conductive tube (I\'m thinking aluminum) so that when it comes out the other side, heat has hopefully been transferred to the water, leaving me with cool airHow can I optimize such a system shape/size.wise (or will it work at all)? Also, I\'m guessing there might be some level of condensationCould I place a desiccant at the end of the tube and expect it to remove much of the moisture without also removing the coldness of the air?- Also, in some ways, while my design is a bit like a swamp/evaporative cooler.minus the need for a more powerful fan to push air through the sponge and a motor to keep pumping water into the sponge.I don\'t want to build a swamp cooler (e.gwith a need for powering moving parts other than just the fan).The idea is not new, and some central air conditioners use water circulation that is cooled by main chiller, which, in turn, cooled by the main refrigeration systemThe swamp/evaporative cooler works entirely on a different principle, and is, actually, useless with hot humid environment.Other related question
