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 Global price level, as reported by the World Bank, is a way to compare the cost of living between different countries. It's measured using Purchasing Power Parities (PPPs), which help us understand how much money is needed to buy the same things in different places. Price level indexes (PLIs), with the world average set at 100, are ...

The process has a high energy consumption, for example around 2,500 kWh (9,000 MJ) of electricity per tonne of sodium hydroxide produced. Because the process yields equivalent amounts of chlorine and sodium hydroxide (two moles of sodium hydroxide per mole of chlorine), it is necessary to find a use for these products in the same proportion.
For watering plants to use sodium chloride (NaCl) as a fertilizer, moderate concentration is used to avoid potential toxicity: 1–3 grams (0.035–0.106 oz) per liter is generally safe and effective for most plants. [19] [20] [21]
A Reuters investigation earlier this year found most of the chemicals are shipped to the U.S. disguised as low-cost goods to evade detection. The ingredients are then routed to Mexico by ...
