  2. Prices of chemical elements - Wikipedia

    en.wikipedia.org/wiki/Prices_of_chemical_elements

    This implicitly puts the value of compounds' other constituents, and the cost of extraction of the element, at zero. ... Bromine: 3.122: 2.4 (6.648 ...

  3. Bromine - Wikipedia

    en.wikipedia.org/wiki/Bromine

    Bromine is a chemical element; it has symbol Br and atomic number 35. ... For many applications, organobromides represent a compromise of reactivity and cost.

  4. Bromine production in the United States - Wikipedia

    en.wikipedia.org/wiki/Bromine_production_in_the...

    Since 2007, all US bromine has been produced by two companies in southern Arkansas, which extract bromine from brine pumped from the Smackover Formation. At an advertised price of US$3.50 to US$3.90 per kg, the US 2013 US production would have a value of roughly US$800 million.

  5. Krypton - Wikipedia

    en.wikipedia.org/wiki/Krypton

    Like the other noble gases, krypton is chemically highly unreactive. The rather restricted chemistry of krypton in the +2 oxidation state parallels that of the neighboring element bromine in the +1 oxidation state; due to the scandide contraction it is difficult to oxidize the 4p elements to their group oxidation states. Until the 1960s no ...

  6. Radium bromide - Wikipedia

    en.wikipedia.org/wiki/Radium_bromide

    This was the reason radium bromide became one of the most expensive materials on earth. In 1921, it was stated in Time magazine that one ton of radium cost 17,000,000,000 Euros, whereas one ton of gold cost 208,000 Euros and one ton of diamond cost 400,000,000 Euros. [6] Radium bromide was also found to induce phosphorescence at normal ...

  7. Densities of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Densities_of_the_elements...

    The following molar volumes and densities for the majority of the gaseous elements were calculated from the van der Waals equation of state, using the quoted values of the van der Waals constants. The source for the van der Waals constants and for the literature densities was: R. C. Weast (Ed.), Handbook of Chemistry and Physics (53rd Edn ...

  8. Bromine compounds - Wikipedia

    en.wikipedia.org/wiki/Bromine_compounds

    Bromine compounds are compounds containing the element bromine (Br). These compounds usually form the -1, +1, +3 and +5 oxidation states. Bromine is intermediate in reactivity between chlorine and iodine, and is one of the most reactive elements.

  9. Berkelium - Wikipedia

    en.wikipedia.org/wiki/Berkelium

    Berkelium-249 is a common target nuclide to prepare still heavier transuranium elements and superheavy elements, [86] such as lawrencium, rutherfordium and bohrium. [16] It is also useful as a source of the isotope californium-249, which is used for studies on the chemistry of californium in preference to the more radioactive californium-252 ...
