Nobelium

Pronounced

no-BELL-i-em

Nobelium (No) is a radioactive metal that has the atomic number 102 in the periodic table, its appearance is not fully known due to the minuscule amounts produced of it. It is an Actinoid Metal with the symbol No.

Nobelium is a synthetic chemical that is created in the lab and is named after Alfred Nobel the inventor of dynamite. The discovery of Nobelium was claimed by Swedish and Soviet scientists. But it was not until 1966 that Soviet scientists proved their discovery. Isotopes of Nobelium are produced by bombarding actinide together to produce Nobelium and nuclear decay. Nobelium has only scientific uses. It is a solid metal at room temperature and it has a melting point of 827°c predicted, the boiling point is unknown.
