...accounts for 0.44 percent of the Earth's crust.
...has a relative density of 4.49 g/cm3.
...has the atomic number 22.
...was not used in industry until the 1950's, primarily in the construction of satellites, rockets and aircraft.
...is used in the form of titanium oxide to desulphurize the exhaust gases of power stations.
...does not react to magnetism.
...does not trigger any skin reactions.
...is resistant to salt water, perspiration and acids.
...on contact with oxygen, forms an even oxide layer with a gray shimmer which acts as a protective coating.
...can only be worked with extremely hard tools.
...has an extremely high melting point of 1800 degrees Celsius.
...can be cast and soldered only in a vacuum.
