The element I selected for the Element Research Project is Osmium. Osmium’s chemical symbol is Os. Osmium’s atomic mass is 190 amu. Osmium’s atomic number is 76, it has 76 protons and 76 electrons. Osmium also has 114 neutrons. Osmium belongs to the transition metal group in the middle of the periodic table.
Osmium’s Bohr model with electric configuration has two electrons in the first shell, eight in the second shell, eighteen is the third shell, thirty two in the fourth shell, fourteen in the fifth shell, and two in the sixth and last shell. Or just 4f14 5d6 6s2. Osmium was discovered by a British Chemist, Smithson Tennant. He discovered it in the residue left behind when crude platinum was dissolved by aqua regia. Osmium originates from …show more content…
Osmium is also used in making instrument pivots, a writing instrument. Osmium tetroxide, OsO4, the same material that is used to detect finger prints, is used to stain fatty tissue to distinguish it on a microscope slide. Osmium is not reactive until it is heated. When Osmium is heated it forms the higly toxic gas, Osmium Tetroxide. Although Osmium Tetroxide is a highly toxic and dangerous gas it has many different uses. Osmium doesn’t react with air at room temperature, but finely divided Osmium oxidizes in air to produce the poisonous, volatile, and strong-smelling Osmium tetroxide (OsO4). Osmium is the heaviest known element. Osmium is also one of the six-member platinum family of precious metals, in group VIII. Osmium has the highest melting point of all the elements.
Scientists in the middle of the eighteenth century thought that the black residue left behind from platinum being dissolved in aqua regia was plasma, when in reality it was Osmium. Osmium is also that rarest of all the stable elements. Osmium is only found in 0.05 parts per billion in the Earth's crust. When Osmium is in its powdered form it can be sold commercially for $1300. Osmium is also used in many
