The oxidation state +4 is the only stable state for the latter two elements and therefore rutherfordium should also exhibit a stable +4 state. [72] In addition, rutherfordium is also expected to be able to form a less stable +3 state. [2] The standard reduction potential of the Rf 4+ /Rf couple is predicted to be higher than −1.7 V. [73]
Named after Mercury, the god of speed and messenger of the Gods, as was the planet Mercury named after the god. · Symbol Hg is from Latin hydrargyrum, which is from the Greek words ὕδωρ and ἀργυρός (hydor and argyros). Meaning "water-silver", because it is a liquid like water (at room temperature), and has a silvery metallic sheen ...
The Joint Institute for Nuclear Research in Dubna (a Russian city north of Moscow), proposed naming element 105 nielsbohrium (Ns) after Niels Bohr, while the University of California, Berkeley suggested the name hahnium (Ha) in honor of Otto Hahn. IUPAC recommended that element 105 be named dubnium, after Dubna.
The chemical element rutherfordium (104 Rf) was named after him in 1997. Early life and education Ernest Rutherford was born on 30 August 1871 in Brightwater , a town near Nelson , New Zealand. [ 14 ]
Fractional Chern insulator: A generalization of fractional quantum Hall state to electrons on a lattice. Berezinskii-Kosterlitz-Thouless state: A 2D state with unbound vortex-antivortex pairs. String-net liquid: Atoms in this state have unstable arrangements, like a liquid, but are still consistent in the overall pattern, like a solid.
Oxidation states rise again only after nobelium, showing that a new series of 6d transition metals has begun: lawrencium shows only the +3 oxidation state, and rutherfordium only the +4 state, making them respectively congeners of lutetium and hafnium in the 5d row. [82]
The equally entrenched name nobelium for element 102 was replaced by flerovium after Georgy Flerov, following the recognition by the 1993 report that that element had been first synthesized in Dubna. This was rejected by American scientists and the decision was retracted. [74] [3] The name flerovium was later used for element 114. [75]
berkelium, Bk, named after Berkeley, where the University of California, Berkeley is located (1949). 98. californium, Cf, named after California, where the university is located (1950). 99. einsteinium, Es, named after Albert Einstein (1952). 100. fermium, Fm, named after Enrico Fermi, the physicist who produced the first controlled chain ...
