Fermium is produced by the bombardment of lighter actinides with neutrons in a nuclear reactor. Fermium-257 is the heaviest isotope that is obtained via neutron capture, and can only be produced in picogram quantities.
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.
The yields are much higher for reactor irradiation, but there, the product is a mixture of various actinide isotopes, as well as lanthanides produced in the nuclear fission decays. In this case, isolation of einsteinium is a tedious procedure which involves several repeating steps of cation exchange, at elevated temperature and pressure, and ...

In 1992, the IUPAC Trans-fermium Working Group named the nuclear physics teams at Dubna and Berkeley as the co-discoverers of element 103. When IUPAC made the final decision of the naming of the elements beyond 100 in 1997, it decided to keep the name "lawrencium" and symbol "Lr" for element 103 as it had been in use for a long time by that point.
Chart newcomer Kenya Grace has made history as her debut single “Strangers” reached the No 1 spot. Born in South Africa but raised in Southampton, Grace began releasing music independently in ...
Also found among the Roman coins were 72 gold aurei, dated from 18 B.C. to 47 A.D. Those coins show no signs of wear and likely came from a pile of freshly minted coins, according to the Cultural ...
Fermium (100 Fm) is a synthetic element, and thus a standard atomic weight cannot be given. Like all artificial elements, it has no stable isotopes. The first isotope to be discovered (in fallout from nuclear testing) was 255 Fm in 1952. 250 Fm was independently synthesized shortly after the discovery of 255 Fm.
