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]
Vanadium (named after Vanadís, another name for Freyja, the Scandinavian goddess of fertility) was originally discovered by Andrés Manuel del Río (a Spanish-born Mexican mineralogist) in Mexico City in 1801. He discovered the element after being sent a sample of "brown lead" ore (plomo pardo de Zimapán, now named vanadinite).
Named after the US state of Tennessee, itself named after the Cherokee village of áážá (tanasi), where important work for one of the steps to synthesise the element was done in the Oak Ridge National Laboratory. · Former names: eka-astatine, [21] ununseptium (Uus, '117'): temporary systematic name and symbol. [61] Oganesson (Og) 118
Low oxidation states are not well-represented for zirconium and hafnium [28] (and should be even less well-represented for rutherfordium); [30] the +3 oxidation state of zirconium and hafnium reduces water. For titanium, this oxidation state is merely easily oxidised, forming a violet Ti 3+ aqua cation in solution. The elements have a ...
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 ]
In 1997 the International Union of Pure and Applied Chemistry settled the dispute: element 104 was given the name suggested by the American research team, rutherfordium, after the influential British physicist. Element 105 was subsequently given the name dubnium, representing the city, Dubna, where the Russian team worked. [10]
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]
