  2. Prices of chemical elements - Wikipedia

    en.wikipedia.org/wiki/Prices_of_chemical_elements

    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 ...

    As of 2003, the two sites produce 0.25 grams and 0.025 grams of 252 Cf per year, respectively. [57] Three californium isotopes with significant half-lives are produced, requiring a total of 15 neutron captures by uranium-238 without nuclear fission or alpha decay occurring during the process.

  6. Transuranium element - Wikipedia

    en.wikipedia.org/wiki/Transuranium_element

    Transuranic elements are difficult and expensive to produce, and their prices increase rapidly with atomic number. As of 2008, the cost of weapons-grade plutonium was around $4,000/gram, [2] and californium exceeded $60,000,000/gram. [3] Einsteinium is the heaviest element that has been produced in macroscopic quantities. [4]

  9. Einsteinium - Wikipedia

    en.wikipedia.org/wiki/Einsteinium

    Its density of 8.84 g/cm 3 is lower than that of californium (15.1 g/cm 3) and is nearly the same as that of holmium (8.79 g/cm 3), despite einsteinium being much heavier per atom than holmium. Einsteinium's melting point (860 °C) is also relatively low – below californium (900 °C), fermium (1527 °C) and holmium (1461 °C).
