Very few properties of rutherfordium or its compounds have been measured; this is due to its extremely limited and expensive production [70] and the fact that rutherfordium (and its parents) decays very quickly. A few singular chemistry-related properties have been measured, but properties of rutherfordium metal remain unknown and only ...
Rutherfordium is expected to be a solid under normal conditions and have a hexagonal close-packed crystal structure (c / a = 1.61), similar to its lighter congener hafnium. [33] It should be a metal with density ~17 g/cm 3. [44] [45] The atomic radius of rutherfordium is expected to be ~150 pm.
The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
Rutherfordium: Dubnium: ... flerovium was a metal or a noble gas was still open with the known evidence: one study suggested a weak noble-gas-like interaction ...
When an alkali metal is dropped into water, it produces an explosion, of which there are two separate stages. The metal reacts with the water first, breaking the hydrogen bonds in the water and producing hydrogen gas; this takes place faster for the more reactive heavier alkali metals. Second, the heat generated by the first part of the ...
Oganesson is expected to be a very poor "noble gas" and may even be metallised by its large atomic radius and the weak binding of the easily removed 7p 3/2 electrons: certainly it is expected to be a quite reactive element that is solid at room temperature and has some similarities to tin, as one effect of the spin–orbit splitting of the 7p ...
Most definitions of the term 'refractory metals' list the extraordinarily high melting point as a key requirement for inclusion. By one definition, a melting point above 4,000 °F (2,200 °C) is necessary to qualify, which includes iridium, osmium, niobium, molybdenum, tantalum, tungsten, rhenium, rhodium, ruthenium and hafnium.
