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 ...
Cost: $5 million per gram Red diamonds are the rarest version of colored diamonds in the world, with no specimens at all being presented to the Gemological Institute of America for grading from ...
This fascination continues today. ... Californium 252. Cost: $27 million per gram. Californium is a rare element that is man-made and not found in nature. As the name suggests, the element was ...
Californium is a silvery-white actinide metal [12] with a melting point of 900 ± 30 °C (1,650 ± 50 °F) and an estimated boiling point of 1,743 K (1,470 °C; 2,680 °F). [13] The pure metal is malleable and is easily cut with a knife. Californium metal starts to vaporize above 300 °C (570 °F) when exposed to a vacuum. [14]
Curium-248 is favored for research purposes due to its long half-life. The most efficient way to prepare this isotope is by α-decay of the californium isotope 252 Cf, which is available in relatively large amounts due to its long half-life (2.65 years). About 35–50 mg of 248 Cm is produced thus, per year.
In a report Tuesday, S&P Global Mobility reckoned that “importers are likely to pass most, if not all, of this (cost) increase to consumers.’’ TD Economics notes that average U.S. car prices ...
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]
Wall Street analysts expect gold's rally to keep going in 2025 after the precious metal saw its biggest annual jump in 14 years. On Thursday, gold futures jumped more than 1% to hover above $2,670 ...
