Nobelium is an artificial chemical element, solid, metal, actinoid, radioactive, unstable, atomic number 102. Nobelium has 12 isotopes and 3 nuclear isomers. Any physical property of nobelium was measured (excepting nuclear properties of the isotopes); some properties are only estimated. Probably nobelium is a reactive metal but we haven't sufficient material for a study and also No is very unstable. Nobelium chlorides were mentioned. Valences are +2 and +3.
Nobelium is a synthetic element, number 102. It is not a compound. See http://en.wikipedia.org/wiki/Nobelium for more information.

The Synthetic Element Nobelium was named for Him.
Nobelium is a member of the actinoids family: before nobelium in the periodic table is mendelevium and after nobelium is lawrencium. It is supposed that nobelium is similar to ytterbium.
