Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide , it can be reduced to produce a lustrous transition metal with a silver color , low density , and high strength, resistant to corrosion in sea water , aqua regia , and chlorine .
Believing this to be a new discovery, Klaproth named it titanium after the Titans of Greek Mythology, but eventually it was clarified that Gregor made the discovery first. Gregor was credited with the discovery, but the element kept the name chosen by Klaproth. Gregor later found titanium in corundum from Tibet, and in a tourmaline from a local ...
41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...
It was recognised as an element by Guyton de Morveau, Lavoisier, Berthollet, and Fourcroy in 1787. [6] The earliest gold artifacts were discovered at the site of Wadi Qana in the Levant. [13] Silver is estimated to have been discovered in Asia Minor shortly after copper and gold. [14] There is evidence that iron was known from before 5000 BC. [15]
A longer-lived isotope 231 Pa was found in 1918 by Otto Hahn and Lise Meitner, and was named by them protactinium: since it is longer-lived, it gave the element its name. [170] [171] William Crookes in 1900 reported his discovery of the radioelement "uranium X", that later was proven to be mixture of uranium X 1 (234 Th) and uranium X 2 (234m ...
Not classified as an element until the 1780s, tungsten likely first popped up in German chemistry as ‘Wolfram,’ and Brahe’s medicine were known to have German influence. “Maybe Tycho Brahe ...
William Gregor of Cornwall was the first to identify the element titanium in 1791, correctly concluding that he had found a new element in the ore ilmenite from the Menachan valley. He proposed the name "menachanite", but his discovery attracted little attention.
