Rutherfordium is a synthetic chemical element; it has symbol Rf and atomic number 104. It is named after physicist Ernest Rutherford. As a synthetic element, it is not found in nature and can only be made in a particle accelerator. It is radioactive; the most stable known isotope, 267 Rf, has a half-life of about 48 minutes.
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 ...
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).
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 ]
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]
On May 30, 1898, Ramsay separated a noble gas from liquid argon by difference in boiling point. [150] 10 Neon: 1898 W. Ramsay and W. Travers 1898 W. Ramsay and W.

A more progressive extraction process involves directly reducing (a low grade) manganese ore in a heap leach. This is done by percolating natural gas through the bottom of the heap; the natural gas provides the heat (needs to be at least 850 °C) and the reducing agent (carbon monoxide). This reduces all of the manganese ore to manganese oxide ...
Karl Ernst Claus, a Russian scientist of Baltic-German ancestry, discovered the element in 1844 at Kazan State University and named it in honor of Russia, using the Latin name Ruthenia. Ruthenium is usually found as a minor component of platinum ores; the annual production has risen from about 19 tonnes in 2009 [9] to some 35.5 tonnes in 2017. [10]
