How much are the elements on the periodic table worth or what would they cost?
81515
hi there, i have a great webpage for you.\n\nthis guy built a "periodic table table" - a big table in his garage made out of wood, and a storage space underneath each element in the table that can be opened up.  inside the box he has stored various samples of that element.  all of this information is online, and includes pictures and information including the price he paid for each one.  it's great.\n\nhere's the site:\nhttp://theodoregray.com/PeriodicTable/\n\nscroll down a bit and click somewhere on the wooden table to see what he has for that element.\n\nEDIT:  i guess i should add, a lot of his samples are listed as "donated" but usually include a link to whatever supplier donated them, and i think you could probably follow the link to find out the cost. \n\nmore info here: \nhttp://theodoregray.com/PeriodicTable/HowToGetOne.html\n\ncheers!

The best bet is to go to a chemistry website and see if there is an explanation of chemical formulas. Also, you should be able to download the periodic table, showing all the elements.

The first 92 elements of the periodic table occur naturally (from hydrogen to uranium).\n\nBTW, in reference to earlier poster, some of the naturally occurring elements (radon, radium, uranium, others) are radioactive, as well.

Could you be a little more specific?  Are you asking how the atomic weights in the periodic table derived?

First, it seems to have only 2 isotopes.  \n\nYou need to take each mass and multiply by its percentage.  Then add the two resulting numbers together.  You then have the weighted average mass for the element, or average atomic mass.  This weighted average atomic mass is the one reported on the periodic table of elements.\n\n35 x 40%\n+\n37 x 60%

If in greatcondition it most likely is worth at least five hundred.  It may be worth more.  \n...A nice one and sure is accurate

rhodium is going for about $4500 an oz these days\n\ncurrent and historical pricing is available at many sites that track and sell precious metals such as:\n\nhttp://www.kitco.com/charts/rhodium.html

It's "worth" whatever a person is willing to pay for it.  It's estimated current value is about $40, but again it all depends on what collectors are willing to pay.

Due to a rise in copper prices in 1973 the mint resolved to do away with copper cents. 1.5 million aluminum cents dated 1974 were produced by the Philadelphia Mint. Opposition by the vending machine industry caused Congress to change its mind. All the aluminum cents were ordered to be recalled, counted and melted. None were released to the public. Only 12 examples remain unaccounted for, not counting one example in the Smithsonian. Several Congressmen and other government officials who were recipients of this experimental issue either claimed the pieces were lost or refused to return them.\n\nAs far as the worth, click then read the link below.

Use the periodic table of the elements.  The "weights" are in grams per mol.  Just use algebra and solve for the number of mols.  Then you know how many atoms there are by the number of mols which is a definite number.

Do a search for the isotopes of gold.  The list should give you each of the isotopes with its "mass number" (there are about 35 isotopes beginning with Au-172 and going through Au-205. ) The mass number is the total number of protons + neutrons.  Since gold is element #79 all of its isotopes have 79 protons so just subtract 79 from the mass numbers to get the neutrons.  Assuming we are talking about neutral gold atoms, the electrons = protons = 79.

I suppose mass is a fairly easily measured value. Compared to finding the number of atoms, it's easier to just stick a sample on a scale/balance and weigh it.\n\nAnd the masses provided on the periodic table are weighted averages of the different isotopes found in nature.

I'm guessing you found some commemorative coins or something similar.  Depending on how much it cost and what each coin weighs if they are all pure silver they would be at least worth their weight at current silver prices.  But as far as collectible value on them I would say $0 since probably every Ace in the country is selling them.\n\nThe silver price is pretty high compared to a year ago and going up steadily so if you can get an accurite weight on them (in oz) and its below current scrap prices you could buy and just sell them as scrap for a profit.  \n\nhttp://goldinfo.net/metals.html (contains current silver prices)

Rhodium is the most valuable metal at $4,180.00(U.S.) per ounce.

I has about one ounce of gold. It is a common date. $20 gold pieces in general are worth a little more than the gold content. The value is dependent on the condition. If it is uncirculated--no wear--it is worth the most. With gold currently at $641, I would guess about $700. An uncirculated coin maybe $750. If it is soldered to the chain, that will lower the value to the price of gold.

ignoring radioactivity(which deals with unstable isotopes) the elements are indestructible and will last forever.\nthe law of conservation of matter says matter can never be created nor destroyed.( we can destroy matter in nuclear bombs but otherwise...).\nAs long as atoms exist, which is forever, the periodic table will tell you what to expect.
