Density: 4507 kg m-3 Melting Point: 1941 [or 1668 °C (3034 °F)] K Boiling Point: 3560 [or 3287 °C (5949 °F)] K Symbol: Ti  Name:Titanium Protons:11 Neutrons:22 Electrons:11 Atomic Mass: 47.867 Atomic Number:22 Electron Configuration: [Ar].3d2.4s2 Orbital Notation:

Valence Electrons:12 The Founder Of the Element: William Gregor When: 1791 in England How: the presence of a new element, now known as titanium, in menachanite Chemical Properties: Physcial Properties:
 * Density Of soild 4507 kg m-3
 * Molar Volume 10.64 cm3
 * Veolocity of Sound 4140 m s-1
 * Vickters Hardness 970 MN m-2

Minerals Founded: oxide layer that usually renders it inactive. However, titanium will react with steam form the dioxide, titanium(IV) oxide, TiO2, and hydrogen, H2. Common Chemical Reactions: Titanium metal does not react with mineral acids at ambient temperature but does react with hot hydrochloric acic to form titanium(III) complexes. titanium starts to burn in air it burns with a spectacular white flame to form titanium dioxide, TiO2 and titanium nitride, TiN Commerical Uses: replacement parts, including hip ball and sockets. These may last for 20 years or so. Titanium is used in dental implants because it is able to "osseointegrate" The Cost: $11.50/pound Diagram Of bohrs model Unsual facts: crystalline igneous rock, in the Manaccan valley in Cornwall, England. He called the new substance manaccanite. Four years after Gregor discovered manaccanite, German chemist Martin Heinrich Klaproth discovered a substance he called titanium in the ore of rutile, a crystalline mineral found in metamorphic and igneous rocks. Eventually, mineralogists realized that both men had discovered the same element. Words Cited
