Question:
How do you figure out the charge for an element on the Periodic Table of Elements?
Aluminum's Atomic Number is 13Mass is 27Protons and Electrons is 13Neutrons is 14Charge is +3How do I figure charge out for other elements?
Answer:
Don't confuse pollution and landfills with global warmingExcept for recycling aluminum, most recycling is energy-inefficient and contributes to carbon dioxide ( if you think THAT contributes to global warming )Landfills probably contribute because they generate methane which, if not captured, is a much more potent greenhouse gas than CO2 Much recycling is wasteful of time and energy but makes the ignorant feel goodMcDonald's switched from plastic to paper-fiber even after an analysis showed that the polystyrene foam had a smaller effect on the environment than the paperIt would have been bad PR to keep the plastic
YES RECYCLING REALLY HELPSTESCO AND OTHER SUPERMARKETS HAVE RECYCLING
Yes, if you don't recycle, dumps will get bigger creating pollution.
welluhhummmthats a good questionyou see, i would thing that recycling is bad for global warming because you have set things on fire and suchSo actually, recyling isnt good for global warming, it's just good for the environmentThink about it, you have paer to recyle? it saves trees and when people cut down trees, it creates pollution which impacts the global warming factorand paper, all they do is get water, shred paper, and put the shredds in one little flat drainging thing, and that makes recyled paperbut for cans, they melt the cans with fireso it really depends on what you're recylingPaper is the best to recycle, not metalsNow for your apartment, go around ask people what they do for recycling.

Elements situated in a column in the periodic table will form ions with the same charge, and share similar propertiesegChlorine, Bromine, Fluorine all ionize to form an ion with a negative 1 chargeIf you don't know, and only have the number of electrons, you can use shell theory (though they'll tell you it's totally wrong at the College and University level, it's good enough for highschool chem)The first shell holds 2 electronsEach shell after that holds 8Once you've filled all the lower shells, whatever's left over is likely what the charge is going to be The other rule of thumb is that if the outer shell electrons are less than 4, the ion will be positiveMore than 4, the ion will be negativeAt 4, the ion might not have a charge at all, as those are usually covalent, but sometimes they take it to be +4 or -4 depending on the compoundUsing your example, elemental Aluminum is neutralIn that state, if you use the shell model, the shells fill up like this: 2+8+3 As the outer shell has 3 electrons, when it forms an ion, it gives up those 3 electrons, making the ion less negative (iemore positive)Thus, it has a charge of +3The reason why college instructors and university profs don't want you relying on the shell model is that it only works for the elements in the simplified periodic table and it's also possible to break the rules even with those elements under some controlled conditions.
