This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
[j] The total amount of astatine in the Earth's crust (quoted mass 2.36 × 10 25 grams) [108] is estimated by some to be less than one gram at any given time. [8] Other sources estimate the amount of ephemeral astatine, present on earth at any given moment, to be up to one ounce [ 109 ] (about 28 grams).
Astatine compounds are compounds that contain the element astatine (At). As this element is very radioactive, few compounds have been studied.
Astatine bromide is produced by the reaction of astatine with an aqueous solution of iodine monobromide: At 2 + 2 IBr → 2 AtBr + I 2 [ 1 ] Astatine bromide also can produce by reacting elemental astatine and bromine : [ 2 ]

There are eight atoms in an orthorhombic unit cell so that gives a density (from the above calcs for metallic astatine) of 278.96 x 10^(–23) grams/412.3276 cubic Å = 6.76 grams per cubic centimetre, noting it is likely to be less than this given stronger intralayer bonding. For comparison, the figure cited in the article is 6.35 ±0.15.
When the s.a.w. is in interval-notation, its conventional value is added too. Data is retrieved from central s.a.w. values lists, formatting is by {{Infobox element/standard atomic weight format}} (same as {{infobox element}}). Example:
