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.
Radioactive elements, except tritium and carbon-14, have been mostly filtered from the water that is being released into the Pacific Ocean.
The fictional metals duranium and tritanium were referred to in many episodes as extremely hard alloys used in starship hulls and hand-held tools. The planet-killer in "The Doomsday Machine" had a hull made of solid neutronium, which is capable of withstanding a starship's phasers. Neutronium is considered to be virtually indestructible; the ...
Radioluminescent keychains. Tritium lighting is made using glass tubes with a phosphor layer in them and tritium gas inside the tube. Such a tube is known as a "gaseous tritium light source" (GTLS), or beta light (since the tritium undergoes beta decay), or tritium lamp.
Good commercial fish. A very popular fish sold frozen as "Poisson La Perle". Thumbprint emperor (Batardé) Olive-green on upper part, pale grey below. Elliptical black spot, fringed with yellow, behind the pectoral fin. Found in lagoons, channels, mangroves and above sea-grass beds. Solitary most of the time but occasionally found in small schools.
The +4 oxidation state dominates titanium chemistry, [1] but compounds in the +3 oxidation state are also numerous. [2] Commonly, titanium adopts an octahedral coordination geometry in its complexes, [3] [4] but tetrahedral TiCl 4 is a notable exception. Because of its high oxidation state, titanium(IV) compounds exhibit a high degree of ...
