As the element of nuclear energy, uranium has fallen into disrepute at least since the reactor disasters in Chernobyl and Fukushima. For chemists, however, its electronic properties are very interesting and have been providing scientific highlights for a good decade. To the article about uranium on the Fascination Chemistry website.
You can listen to everything about uranium in two and a half minutes on the Deutschlandfunk Kultur podcast.
In addition to lanthanum La, the lanthanides include the 14 elements listed below in the periodic table
All are metals and chemically similar.
The actinides include actinium and the 14 following elements in the periodic table:
All actinides are radioactive metals. The heaviest naturally occurring element is uranium with atomic number 92 (sometimes plutonium (94) is also mentioned as the heaviest naturally occurring element because it can occur in tiny traces through the decay of other elements in rocks).
