Nobelium is a synthetic chemical element with the symbol No and atomic number 102. It is named in honor of Alfred Nobel, the inventor of dynamite and benefactor of science. A radioactive metal, It is named after Alfred Nobel, the inventor of dynamite. It is a man-made element made in low quantities. It is a part of the actinide series. Until now twelve isotopes have been determined among them 259 No is the most stable isotope.
It is predicted that Nobelium is a divalent metal. The behavior of this metal is better known only in aqueous solution. Hence a lot of the properties of the element are unknown. An atom of Nobelium consists of a hundred and two electrons. Three of these electrons behave as valence electrons.
Although the Swedish scientists soon retracted their claims, the priority of the discovery and therefore the naming of the element was disputed between Soviet and American scientists, and it was not until 1997 that International Union of Pure and Applied Chemistry (IUPAC) credited the Soviet team with the discovery, but retained nobelium, the Swedish proposal, as the name of the element due to its long-standing use in the literature.
Characteristics of Nobelium
- In the periodic table, nobelium is located to the right of the actinide mendelevium, to the left of the actinide lawrencium, and below the lanthanide ytterbium.
- Nobelium metal has not yet been prepared in bulk quantities, and bulk preparation is currently impossible.
- Nevertheless, a number of predictions and some preliminary experimental results have been done regarding its properties.
- The chemistry of nobelium is incompletely characterized and is known only in aqueous solution, in which it can take on the +3 or +2 oxidation states, the latter being more stable.
- It is highly radioactive and is a synthetic metal. It can be produced by nuclear bombardment that is by irradiating a californium-249 target with carbon-12 ions. (1b).
