I found this online: Cut and paste from www.funtrivia.com/askft/Question143123.html
$16,000,380,209,200.2842
So here is a more detailed version. There are a lot of more practical considerations to consider, like
a) Preparation and transportation costs for the more dangerous ones.
b) You can’t necessarily get everything this cheap due to many of the metals being at bulk rates. I know from looking on ebay that you’d have to spend a lot more than the listed price for a sample of pure tungsten, for example. When a price vs a bulk price was given, I used the non-bulk price.
c) You need special clearances for things like plutonium.
d) A few micrograms of polonium are incredibly deadly, a whole 1 g would be insane, so the price shouldn’t be a surprise.
e) Some of them, while purchasable at small amounts, do not necessarily have as much as 1 g available. For example, a grand total of 0.66 g of berkelium was made over the course of 16 years (1966 – 1983). Requesting a full gram of it might cause other unique issues.
f) Some elements essentially cost nothing, depending in part on how pure you want them to be.
g) Different websites are giving very different prices for things like the lanthanides. I picked what seem to be the most up-to-date prices.
Of those elements that CAN be purchased in some way or another, the prices per gram are:
99 & above: unobtainable
98 – Californium – $60 million (cheapest isotope)
http://www.osti.gov/scitech/servlets/purl/15053
http://www.speclab.com/elements/californium.htm
97 – Berkelium – $160 million
http://www.3rd1000.com/elements/Berkelium.htm
https://en.wikipedia.org/wiki/Berkelium#Synthesis_and_extraction
96 – Curium – $160 million (cheapest isotope)
http://www.speclab.com/elements/curium.htm
95 – Americium – $1500 (most commonly cited cost)
http://www.speclab.com/elements/americium.htm
94 – Plutonium – $4000
http://hypertextbook.com/facts/2008/AndrewMorel.shtml
93 – Neptunium – $660
http://www.chemistry.pomona.edu/chemistry/periodic_table/Elements/Neptunium/the%20facts.htm
92 – Uranium – $0.07
For this one, it seems that U3O8 is what’s available. Considering that it’s $25.75/lb and 85% U, I did conversions to get to that.
http://www.uranium.info/
91 – Protactinium – $280
http://www.chemicool.com/elements/protactinium.html
90 – Thorium – $5.29
https://www.hobart.k12.in.us/ksms/PeriodicTable/thorium.htm
89 – Actinium (not available)
Some sites are saying $100 per gram but they look suspect, most say not available.
88 – Radium – $100,000
https://www.hobart.k12.in.us/ksms/PeriodicTable/radium.htm
87 – Francium – (essentially nonexistent)
86 – Radon – $102,000
There are extremely conflicting results on the cost of radon and it’s not clear what units most of them are supposed to represent. So for this, I assume you take radium-223 and let it decay to radon-219 (half-life is 11.43 days), adjusting the price of radium accordingly.
https://en.wikipedia.org/wiki/Radium
85 – Astatine – (essentially nonexistent)
84 – Polonium – $16,000,000,000,000
http://education.jlab.org/itselemental/ele084.html
http://www.theglobeandmail.com/news/world/polonium-is-costly-undetectable-trillion-times-more-toxic-than-cyanide/article18179025/
Converted cost from microcuries to grams according to these two. Polonium is incredibly deadly in extremely small quantities.
83 – Bismuth – $0.11
https://www.hobart.k12.in.us/ksms/PeriodicTable/bismuth.htm
82 – Lead – $ 0.002
http://www.infomine.com/investment/metal-prices/
81 – Thallium – $5.17
http://minerals.usgs.gov/minerals/pubs/commodity/thallium/thallmcs07.pdf
80 – Mercury – $0.017
http://www.chemicool.com/elements/mercury.html
79 – Gold – $43
https://www.google.com/search?q=price+of+gold
The price of gold changes constantly (most prices do but few are as available as gold is), so I rounded to the nearest dollar.
78 – Platinum – $34
https://www.google.com/search?q=price+of+platinum
As with gold.
77 – Iridium – $19
https://taxfreegold.co.uk/iridiumpricesusdollars.html

76 – Osmium – $13
https://taxfreegold.co.uk/osmiumpricesusdollars.html

74 – Tungsten – $0.044
http://www.playfairmining.com/s/NewsReleases.asp?ReportID=515163
73 – Tantalum – $0.133
http://www.infomine.com/investment/metal-prices/tantalite-ore/6-month/
Available as “tantalite ore”, without a specific composition, so this price is not exact – probably off by a few cents.
72 – Hafnium – $1

30 – Zinc – $0.002
http://www.infomine.com/investment/metal-prices/
29 – Copper – $0.0032
http://www.infomine.com/investment/metal-prices/
While copper costs $2.10 per pound at the moment, a pre-1982 American cent is readily available and contains 3.1 g of it. This cuts a whole $0.002 off the total cost.
28 – Nickel – $0.0085
http://www.infomine.com/investment/metal-prices/
Like copper, but older Canadian nickels have more than their value in nickel. Otherwise it’s about $4.50 per pound ot $0.01 per gram.
27 – Cobalt – $0.025
http://www.infomine.com/investment/metal-prices/
26 – Iron – $0.047 (for pure iron, steel is much less)

24 – Chromium – $0.32
http://www.chemicool.com/elements/chromium.html
23 – Vanadium – $0.045
http://www.radiochemistry.org/periodictable/elements/23.html
I used the 95% pure value, because I thought that’s good enough. The 99.9% is quite a bit more.
22 – Titanium – $6.60
http://www.chemicool.com/elements/titanium.html
21 – Scandium – $270

13 – Aluminum – $0.002
http://www.infomine.com/investment/metal-prices/
12 – Magnesium – $0.002
http://www.infomine.com/investment/metal-prices/
11 – Sodium – $0.25
http://www.chemicool.com/elements/sodium.html
(for pure sodium, otherwise you could just get it from salt)
10 – Neon – $0.33
http://www.chemicool.com/elements/neon.html
9 – Fluorine – $1.90
http://www.chemicool.com/elements/fluorine.html
Keep in mind that pure fluorine is extremely dangerous and needs to be stored in heavy wax to keep from reacting.
8 – Oxygen – $0.003
http://www.chemicool.com/elements/oxygen.html
This assumes you don’t feel like hydrolyzing it from water. Either way, it’s nearly nothing.
7 – Nitrogen – $0.004
https://www.hobart.k12.in.us/ksms/PeriodicTable/nitrogen.htm
Much like oxygen. Since air is 78% nitrogen you could always claim you have it, but you can get pure, liquid nitrogen if you wanted.
6 – Carbon – $0.024
http://www.chemicool.com/elements/carbon.html
This seems to be if you go out of your way to get some. You could easily get carbon from graphite/pencils, for example. Or you could get the diamond allotrope, which will cost quite a bit more.
5 – Boron – $5
http://www.rareearth.org/boron_properties.htm
Note: results are fairly conflicting for boron.
4 – Beryllium – $0.51
http://moneyweek.com/money-morning-metals-beryllium-11607/
3 – Lithium – $0.27
http://www.chemicool.com/elements/lithium.html
2 – Helium – $0.175
https://www.hobart.k12.in.us/ksms/PeriodicTable/helium.htm
$.0375 per 1 ft3 * 0.0283 m3/ft3 * 0.164 kg/m3 * 1000 g/1 kg
1 – Hydrogen – $1
https://www.hobart.k12.in.us/ksms/PeriodicTable/hydrogen.htm
As with oxygen, you could just hydrolyze water for hydrogen.
If you add up all the relatively cheap ones (less than $1000 each), you get $1700.2842
Add in americium and plutonium, $7200.2842
Add in radon and radium, $209,200.2842
Add in californium, berkelium, and curium, $380,209,200.2842
Add in polonium, $16,000,380,209,200.2842
Yeah, that went up pretty fast.
