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.
The Materials Science Citation Index is a citation index, established in 1992, by Thomson ISI (Thomson Reuters). Its overall focus is cited reference searching of the notable and significant journal literature in materials science .
The journal is abstracted and indexed in the Chemical Abstracts Service, [6] the Science Citation Index Expanded, and selectively in Index Medicus/MEDLINE/PubMed. [7] According to the Journal Citation Reports, the journal has a 2023 impact factor 3.8. [8]
