Why is this element important in everyday life?
Cobalt is essential to everyday life because it is a component of vitamin B12.This prevents pernicious anemia.Cobalt is also used in medicine to destroy certain types of cancer cells.The gamma rays are used to kill bacteria and insects that spoil and infest food.
Cobalt makes up Stellite alloys,dyes,stainless steel,jet turbines,and turbo-super chargers.It can also correct a mineral difficiency in animals.
Where is this element found in nature?
Cobalt occurs in mineral ores such as cobaltite,smaltite,and erythrite.It is also obtained as a by-product of nickel,silver,lead,copper,and iron ores.An amazing fact about cobalt is that it is found in meteorites.It is a free element.Cobalt is also found in meat and dairy products such as liver,shellfish,and oysters.

Who is ?
Hello!I am cobalt and I am here to defend myself on the charge of premeditated murder.First I will inform you of my crime. I am charged with the killing of insects and bacteria.I am an important element found in vitamin B12.It is my job to help people.I help prevent pernicious anemia and destroy certain cancer cells.The insects and bacteria that I "murder" spoil and infest food.This destroys human beings!I am a very kind and gentle element.I am always trying to help others even if it means that I have to destroy harmful bacteria and insects.Sure,maybe my name does mean goblin,but it is only a title,given to me at discovery.I am not a murderer.Maybe I can tell you some more of my good qualities.Ihelp make up Stellite alloys for high-speed,heavy-duty,high-temperature cutting tools.Iam used for dyes,stainless steel,jet turbines, and turbo super chargers.Perhaps this has convinced you to vote that I am innocent Thank you, so much.
