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.
So-called "bromine dioxide", a pale yellow crystalline solid, may be better formulated as bromine perbromate, BrOBrO 3. It is thermally unstable above −40 °C, violently decomposing to its elements at 0 °C. Dibromine trioxide, syn-BrOBrO 2, is also known; it is the anhydride of hypobromous acid and bromic acid. It is an orange crystalline ...
Bromine-bearing brines are associated with saline deposits. The bromine content of sea water is 60 to 70 parts per million (ppm). As sea water evaporates, a succession of minerals precipitate, concentrating the bromine. Bromide is so soluble that it does not form saline minerals.

Abney’s viral video takes place in his car, so it’s only fitting that he took aim at two extortionate driving expenses: insurance and gas. “My car insurance from four-years-ago until now ...
Housing is too expensive – if it’s even available. All real estate is local, of course, and there are very specific reasons why a property in any particular community has the price tag it does.
A traditional method for the manufacture of KBr is the reaction of potassium carbonate with an iron(III, II) bromide, Fe 3 Br 8, made by treating scrap iron under water with excess bromine: [4] 4 K 2 CO 3 + Fe 3 Br 8 → 8 KBr + Fe 3 O 4 + 4 CO 2
Bromism is the syndrome which results from the long-term consumption of bromine, usually through bromine-based sedatives such as potassium bromide and lithium bromide. Bromism was once a very common disorder, being responsible for 5 to 10% of psychiatric hospital admissions, but is now uncommon since bromide was withdrawn from clinical use in ...
