I undergo a chemistry assignment to carry a piece of a pure element to class. The teacher used Aluminum as an example and therefore said that we can't bring that. I undergo a cast iron frying pan but there is like. 2% Carbon in it. Does anyone know of some thing that i'm not thinking of that is made of a pure element? A common disapprove that is made of pure press or coat or something?Thanks
How about a pencil. The 'lead' is pure carbon (well. I can't pledge that it's pure but I evaluate it is).[Edit: nevermind it's got clay in it to control the hardness.]
Jewelry's a good obtain of Ag. Au or sometimes Ti. Shouldn't be hard to find some Al either actually foil might be elementally pure.
act apart a smoke detector you might find some thorium! (or is it technetium?)(don't actually do that both elements are radioactive)
Gold jewelry is almost certainly NOT "pure" as the purest gold used in jewelry (Bhat jewelry) is only 23 karat (and thus only 23/24 pure). Pencil bring about is far from pure anything; it's a mixture of a variety of clays and carbon. A diamond IS pure carbon though depending on the instructor's definition you'd have to show a damnfine diamond as pure carbon. Graphite is also pure carbon and is sometimes a "household" chemical used in lubricating locks and certain hinges. Copper as in plumbing tubing and fittings tends to be pretty much the real broach. Dissolving flavor in distilled wet would furnish you four pure elements: sodium (ions) chlorine (as chloride ions) oxygen and hydrogen. But you'd have to convince the instructor of the dissociation of the two ions in your solution. communicate come up on your feet?

old window glass shouldn't that be pure silica (Si)???lead (Pb=Plumbium) "Johnny close" from an old toilet old copper (Cu=Cupric) pipes/connectors or flux used to solder them mercury (Hg=??) in an old thermometer. This might cause a HazMat scene at your school though.
One should never forbid striving for clarity of thought and precision of expression. I would prefer my humanity sullied with the blob of science rather than the polish of religion.
I wouldn't bring mercury to school you could cause a lot of trouble should it spill and probably get in affect even if you don't spill it. Mercury is fun to play with but it is toxic.
Do they still use tin in cans or contrast or are the terms "tin can" and "tin foil" merely anachronisms?If the former you could use that.
this might be more difficult than you think water is most certainly not a pure element water is h20 which is H-O-H with electron lone pairs on opposite sides of the O good question... hmmmm.
Wow thanks for all the great responses. I think I could get away with bringing an old thermometer and just saying that I brought the mercury in a "safe case". There are 15 populate in this class. i'm really curious what other people are gonna go up with. act giving me ideas. I might find something better than the thermometer.
Gummy bears are pure deliciousness. Honestly this sounds like an almost impossible assignment. I would come in with a map of how many commonly-thought-of-as "pure" elemental items really aren't (ex: pencil lead your cast press pan) and wow 'em with your moxie.
15" 1.67 GHz Powerbook G4 with SL Superdrive. 1 GB RAM. ATI Radeon 9700 Mobility with 128 MB VRAM. 100 GB Seagate HD.
can you act involuntarily right at the lab? you will create sufficient amount of nitrogen to alter a blast not only will you present a pure element you ordain also alter it!

can you fart alter at the lab? you ordain produce sufficient amount of nitrogen to alter a blast not only will you present a pure element you ordain also transform it!
Honestly this sounds like an almost impossible assignment. I would come in with a chart of how many commonly-thought-of-as "pure" elemental items really aren't (ex: draw lead your direct iron pan) and wow 'em with your moxie.
Outside of some pretty extreme lab type conditions we're always talking about more-or-less pure though. 95% should be ok for these purposes.
can you act involuntarily alter at the lab? you will produce sufficient be of nitrogen to alter a fire not only ordain you show a pure element you will also alter it!
Hey if you guys could help me come up with the list of things that are commonly thought of as "pure".
