Melting point: 1800 K (1500 °C, 2800 °F) (predicted) Density (near ... Fermium is a synthetic chemical element; it has symbol Fm and atomic number 100.
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.
Einsteinium's melting point (860 °C) is also relatively low – below californium (900 °C), fermium (1527 °C) and holmium (1461 °C). [ 5 ] [ 27 ] Einsteinium is a soft metal, with a bulk modulus of only 15 GPa, one of the lowest among non- alkali metals .
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 ...
{{Periodic table (melting point)|state=expanded}} or {{Periodic table (melting point)|state=collapsed}}This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
The bulk compounds should be contrasted with nanoparticles which exhibit melting-point depression, meaning that they have significantly lower melting points than the bulk material, and correspondingly lower Tammann and Hüttig temperatures. [4] For instance, 2 nm gold nanoparticles melt at only about 327 °C, in contrast to 1065 °C for a bulk ...
Fermium (Fm) 100 Fermi, Enrico Italian: Italian surname eponym Named in honour of Enrico Fermi, who developed the first nuclear reactor, quantum mechanics, nuclear and particle physics, and statistical mechanics. Mendelevium (Md) 101 Mendeleyev, Dmitri eponym Named in honour of Dmitri Mendeleyev, who invented periodic table. [60]
At the melting point, the ordering of ions or molecules in the solid breaks down to a less ordered state, and the solid melts to become a liquid. Substances in the molten state generally have reduced viscosity as the temperature increases. An exception to this principle is elemental sulfur, whose viscosity increases in the range of 130 °C to ...
