Cobalt Facts and Physical Properties

Atomic Number: 27 Symbol: Co Atomic Weight: 58.9332 Discovery: George Brandt, circa 1735, maybe 1739 (Sweden) Electron Configuration: [Ar] 4s2 3d7 Word Origin: German Kobald: evil spirit or goblin; Greek cobalos: mine Isotopes: Twenty-six isotopes of cobalt ranging from Co-50 to Co-75. Co-59 is the only stable isotope. Properties Cobalt has a melting point of 1495Â °C, boiling point of 2870Â °C, specific gravity of 8.9 (20Â °C), with a valence of 2 or 3. Cobalt is a hard, brittle metal. It is similar in appearance to iron and nickel. Cobalt has a magnetic permeability around 2/3 that of iron. Cobalt is found as a mixture of two allotropes over a wide temperature range. The b-form is dominant at temperatures under 400Â °C, while the a-form predominates at higher temperatures. Uses Cobalt forms many useful alloys. It is alloyed with iron, nickel, and other metals to form Alnico, an alloy with exceptional magnetic strength. Cobalt, chromium, and tungsten may be alloyed to form Stellite, which is used for high-temperature, high-speed cutting tools and dies. Cobalt is used in magnet steels and stainless steels. It is used in electroplating because of its hardness and resistance to oxidation. Cobalt salts are used to impart permanent brilliant blue colors to glass, pottery, enamels, tiles, and porcelain. Cobalt is used to make Sevres and Thenards blue. A cobalt chloride solution is used to make a sympathetic ink. Cobalt is essential for nutrition in many animals. Cobalt-60 is an important gamma source, tracer, and radiotherapeutic agent. Sources: Cobalt is found in the minerals cobaltite, erythrite, and smaltite. It is commonly associated with ores of iron, nickel, silver, lead, and copper. Cobalt is also found in meteorites. Element Classification: Transition Metal Cobalt Physical Data Density (g/cc): 8.9 Melting Point (K): 1768 Boiling Point (K): 3143 Appearance: Hard, ductile, lustrous bluish-gray metal Atomic Radius (pm): 125 Atomic Volume (cc/mol): 6.7 Covalent Radius (pm): 116 Ionic Radius: 63 (3e) 72 (2e) Specific Heat (20Â °C J/g mol): 0.456 Fusion Heat (kJ/mol): 15.48 Evaporation Heat (kJ/mol): 389.1 Debye Temperature (K): 385.00 Pauling Negativity Number: 1.88 First Ionizing Energy (kJ/mol): 758.1 Oxidation States: 3, 2, 0, -1 Lattice Structure: Hexagonal Lattice Constant (Ã…): 2.510 CAS Registry Number: 7440-48-4 Cobalt Trivia Cobalt derived its name from German miners. They named cobalt ore after mischievous spirits called kobalds. Cobalt ores commonly contain the useful metals copper and nickel. The problem with cobalt ore is it usually contains arsenic as well. Attempts to smelt the copper and nickel typically failed and would often produce toxic arsenic oxide gases.The brilliant blue color cobalt gives to glass was originally attributed to bismuth. Bismuth is often found with cobalt. Cobalt was isolated by Swedish chemist, Georg Brandt who proved the coloring was due to cobalt.The isotope Co-60 is a strong gamma radiation source. It is used to sterilize food and medical supplies as well as radiation therapy in the treatment of cancer.Cobalt is a central atom in vitamin B-12.Cobalt is ferromagnetic. Cobalt magnets stay magnetic to the highest temperature of any other magnetic element.Cobalt has six oxidation states: 0, 1, 2, 3, 4, and 5. The most common oxidation states are 2 and 3.The oldest cobalt col ored glass was found in Egypt dated between 1550-1292 B.C.Cobalt has an abundance of 25 mg/kg (or parts per million) in the Earths crust.Cobalt has an abundance of 2 x 10-5 mg/L in sea water.Cobalt is used in alloys to increase temperature stability and decrease corrosion.

Personal Narrative A Missing Piece - 927 Words

A Missing Piece As we watched Parenthood there was one scene that really stuck out to me; Cool’s father left him. I understand completely that it was a movie, but it struck me kind of hard since I understand what it feels like to be left behind. Even though my situation is a little different, I faced the same challenges and emotions. My father didn’t just walk out and leave my sisters and I behind like we were nothing, he passed away leaving a wife and three girls behind. My dad was my best friend, he would always pick me up from pre-school and take me back to his apartment where we would play games and watch movies. At this time my dad, Steve, struggled for many years with dialysis, diabetes, and kidney problems. He went through years and years of treatments and had one kidney and one pancreas transplant; each one failed. Cool’s situation is different compared to mine, for example: he will see his father at some point, and he knows he is still out there. However , it is the same; you feel abandoned, and will be missing that parent to look up to. As I watched that scene, the only thing that traveled through my mind was, he is only 6, and just lost his dad. You can look at his face and see how he doesn’t understand why his dad left him; he also, doesn’t know what that even means or what is happening. This may only be a movie, but the struggles he will go through by not having a father to look up to are imbarable. He will always have that sense of something missing.
