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.
Liquid francium—if created—should have a surface tension of 0.05092 N/m at its melting point. [10] Francium's melting point was estimated to be around 8.0 °C (46.4 °F); [11] a value of 27 °C (81 °F) is also often encountered. [8] The melting point is uncertain because of the element's extreme rarity and radioactivity; a different ...
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. [28]
118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).
Fermium: Mendelevium: Nobelium: Lawrencium: ... Melting point: 2430 K (2157 °C, 3915 °F) Boiling point: 4538 K (4265 °C, 7709 °F) Density (at ...
Scatter plot of electronegativity values and melting points for metals (up to fermium, element 100) and some borderline elements (Ge, As, Se, Sb, Te, At). Elements categorised by some authors as post-transition metals are distinguished by their relatively high electronegativity values, and relatively low melting points (Pt is anomalous in this ...
Ununennium is predicted to have a melting point between 0 °C and 30 °C: thus it may be a liquid at room temperature. [6] It is not known whether this continues the trend of decreasing melting points down the group, as caesium's melting point is 28.5 °C and francium's is estimated to be around 8.0 °C. [ 88 ]
