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.
Though two longer-lived isotopes exist (polonium-209 with a half-life of 124 years and polonium-208 with a half-life of 2.898 years), they are much more difficult to produce. Today, polonium is usually produced in milligram quantities by the neutron irradiation of bismuth .
Polonium-210 (210 Po, Po-210, historically radium F) is an isotope of polonium. It undergoes alpha decay to stable 206 Pb with a half-life of 138.376 days (about 4 + 1 ⁄ 2 months), the longest half-life of all naturally occurring polonium isotopes ( 210–218 Po). [ 1 ]
Heavier elements were mostly produced much later, in stellar nucleosynthesis. Hydrogen and helium are estimated to make up roughly 74% and 24% of all baryonic matter in the universe respectively. Despite comprising only a very small fraction of the universe, the remaining "heavy elements" can greatly influence astronomical phenomena.
How much is an Oscar worth? Massive Oscar statues stand at the entrance of the 2016 Academy Awards in Los Angeles. Despite being Hollywood's most prestigious award, an Oscar trophy is only worth $1.
How much is the aluminum in a can worth? Aluminum can prices vary by region and are based on weight. The average recycling value per pound of cans in the U.S. is currently $0.56.
How much is TikTok worth? Wedbush analyst Dan Ives estimates TikTok is worth “well north of $100 billion” with the algorithm — and potentially up to $200 billion in a “best case scenario
The plutonium was apparently sourced from the Magnox reactors at Calder Hall or Chapelcross. The content of Pu-239 in material used for the 1962 test was not disclosed, but has been inferred to have been at least 85%, much higher than typical spent fuel from currently operating reactors. [29]
