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. 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.

Notes

1. Density for 0 °C, 101.325 kPa. For individual isotopes except deuterium, density of base element is used. Values in parentheses are theoretical predictions.
2. Unless otherwise indicated, elements are primordial – they occur naturally, and not through decay.
3. Price per volume for 0 °C, 101.325 kPa, pure element. For individual isotopes except deuterium, density of base element is used.
4. Prices of hydrogen produced by distributed steam methane reforming, as predicted by H2A Production Model from United States Department of Energy, assuming price of natural gas of US$3/MMBtu (US$10/MWh; US$0.10/m). Does not include cost of storage and distribution.
5. 99.8% pure compressed deuterium gas, in lot size of 850 L (142 g). Also sold by same supplier in the form of heavy water at price of 3940 USD per kg deuterium. In 2016, Iran sold 32 tons of heavy water to United States for 1336 USD per kg deuterium.
