Many of its compounds are deadly poison and used as weed killer and rat poison. Conducts electricity. Used in semiconductors. Some compounds, called arsenides, are used in the manufacture of paints, wallpapers, and ceramics. Found in mispickel (arsenopyrite) a2AbKwAvyos Arsenic
William Gregor found the oxide of titanium in ilmenite in 1791.

Martin Heinrich Klaproth independently discovered the element in rutile in 1795 and named it.

The pure metallic form was only obtained in 1910 by Matthew A. Hunter.

In 1936, the Kroll Process made the commercial production of titanium possible. From the Latin titans, the first sons of the Earth, Greek mythology 33 From the Greek word "arsenikon" meaning "yellow orpiment"

Titanium metal is considered to be non-toxic
Titanium is one of the few elements that burns in pure nitrogen gas
Titanium is used in steel as an alloying element to reduce grain size and as a deoxidizer, and in stainless steel to reduce carbon content.

Titanium has potential use in desalination plants for converting sea water into fresh water.

Titanium is used in several everyday products such as drill bits, bicycles, golf clubs, watches and laptop computers.
