Info of Titanium Atomic Number: 22 Symbol: Ti Atomic Weight: 47.88 Electron Configuration: 4s23d2 Melting Point: 1660 +/- 10°C Boiling Point: 3287°C

Discovery Titanium was being discovered in 1791 at England by William Gregor Named by Klaproth in 1795 Prepared by Nilson and Petterson in 1887

Brief Description Titanium was being classified as a transition metal. It have a colour of silver and dark gray. It appears to be shiny. Titanium burns in air and it’s the only element that burns in nitrogen. There are 13 known isotopes in titanium. Titanium that is natural includes 5 stable isotopes with a 46-50 atomic masses, also it is highly radio active upon bombardment with deuterons. Titanium is present most in igneous rocks and sediments derived from them. It is found in coal ash, plants, human body, sun, and meteorites. It occurs in rutile, ilmenite, sphene, and many iron ores and titanates.

Hazardous Affects To Humans: Corrosion at eye or skin contact Breathing problem by titanium dioxide particles with a small size Lung disease To the environment and animals: May affect risk in water which is toxic in water but only in a small organism and are harmful. Bad air to animals and it may cause also breathing problem.

Uses of Titanium Titanium’s corrosion is useful for ships propellers and rigging Use in desalination plant Can used in missiles and rockets where a light weight heat resistant is required

Interesting Facts Titanium is the 9th most abundant element in the earth’s crust The only element that burns in nitrogen It’s as strong as steel, but 45% of it is lighter and 60% heavier than alumunium, but it’s twice stronger The word “Titanium” is from Latin, titans, which means in mythology, the first son of earth
