At the boiling point the two phases of a substance, liquid and vapor, have identical free energies and therefore are equally likely to exist. Like all elements with atomic number over 100, nobelium can only be produced in particle accelerators by bombarding lighter elements with charged particles. Elements with high ionization energies have high electronegativities due to the strong pull exerted by the positive nucleus on the negative electrons.

The metal dissolves in dilute mineral acids, but concentrated sulfuric acid has little action on it. Its properties cause the colour of the glass to change from purple to yellow to blue or green under different lighting conditions. Early neodymium glasses made in the 1930s have a more reddish or orange tinge than modern versions, which are more cleanly purple, because of the difficulties in removing traces of praseodymium using early technology, namely fractional crystallization. ), and shape.

Generally, the elements on the right side of the periodic table will have large negative electron affinity. Since traces of the element in nature is exceedingly scarce, the element is typically synthesized by bombarding enriched uranium with thermal neutrons to produce promethium-147. Lead is a heavy metal that is denser than most common materials. [42][43][44], Neodymium is classified as a lithophile under the Goldschmidt classification, meaning that it is generally found combined with oxygen. The greater the negative value, the more stable the anion is. J Sustain Met 3(1):122149. They are thus mostly restricted to the mostly ionic cyclopentadienides (isostructural with those of lanthanum) and the -bonded simple alkyls and aryls, some of which may be polymeric.[18]. The most commonly used spontaneous fission neutron source is the radioactive isotope californium-252. The name neodymium is derived from the Greek words neos (), new, and didymos (), twin.
