- 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. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Of those elements, rhodium, caesium and gold have only one stable isotope (133Cs, 103Rh and 197Au respectively), iridium has two (191Ir & 193Ir) whereas palladium and platinum both have several. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars. While the difficulty of obtaining macroscopic samples of synthetic elements in part explains their high value, there has been interest in converting base metals to gold (Chrysopoeia) since ancient times, but only deeper understanding of nuclear physics has allowed the actual production of a tiny amount of gold from other elements for research purposes as demonstrated by Glenn Seaborg. However, both this and other routes of synthesis of precious metals via nuclear reactions is orders of magnitude removed from economic viability. Chlorine, sulfur and carbon (as coal) are cheapest by mass. Hydrogen, nitrogen, oxygen and chlorine are cheapest by volume at atmospheric pressure. When there is no public data on the element in its pure form, price of a compound is used, per mass of element contained. This implicitly puts the value of compounds' other constituents, and the cost of extraction of the element, at zero. For elements whose radiological properties are important, individual isotopes and isomers are listed. The price listing for radioisotopes is not exhaustive. (en)
- 以下列出各個化学元素的價格，主要列舉商品在批量貿易中的平均市面價格，也展示各元素在地球地殼的豐度，以資比較。 截至2020年，按質量和體積而言，最昂貴的非人工合成元素是铑。按質量而言，銠之後的是铯、铱和钯；按體積而言，銠之後的是铱、金和铂。以钻石形式存在的碳可以比銠更昂貴。一些人工合成放射性同位素的每公斤價格可以到達上萬億美元。 按質量而言，氯、硫和碳（煤炭）最便宜；在大氣壓下，按體積而言，氢、氮、氧和氯最便宜。 若沒有公開資料提供某元素在單質形式下的價格，則使用其化合物的價格，按所含元素的質量計算。因此，此計算假定化合物的其他組分的價格和提取成本為零。對於放射性質很重要的元素，下表列出各個同位素和同質異能素的價格。放射性同位素的價目表並不詳盡。 (zh)
