Question:

Electron Configuration of Aluminium is 2,8,3Briefly describe what these numbers mean.?

Please answer this question aboveNot in too much detail hence the 'briefly' also not too hard as I am only doing GCSE Additional not University!Thanks so much :D

Answer:

Just use the foilOr another option is waxed paper.
depends what your using it foryou can wrap food in either to store in fridge/freezer you cant bake with of plastic wrap, but you can use the foil
I don't know what you are making or what you have at your disposal but the short answer is noThe plastic wrap doesn't have anything to make something not stickIn fact many are made with adhesives to make a better sealAnd if you are using an oven then the plastic meltsWax paper is decent alternative and depending on what you're making you might be able to get away with greasing the foil or even using the foil plainBut don't use the plastic wrap.
Atoms have electron shellsEach shell can only contain a fixed number of electronsThe first shell can hold 2 electronsThe second can hold 8The third 18I'm not sure about the fourth or fifthThe Electron Configuration shows that the first shells are filledThe last number is rarely filled unless they are the noble gasesif you notice the last number is also their valency.
