Melting point: 1800 K (1500 °C ... Although the most stable isotope of fermium is 257 Fm, with a half-life of 100.5 days, most studies are conducted on 255 Fm (t 1/2 ...
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.

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).

For example, the melting point of silicon at ambient pressure (0.1 MPa) is 1415 °C, but at pressures in excess of 10 GPa it decreases to 1000 °C. [13] Melting points are often used to characterize organic and inorganic compounds and to ascertain their purity. The melting point of a pure substance is always higher and has a smaller range than ...
Group 8 is a group (column) of chemical elements in the periodic table.It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). [1] " Group 8" is the modern standard designation for this group, adopted by the IUPAC in 1990. [1]
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.
