With these exceptions, the actinide elements are synthetic in origin for practical purposes, ie, they are products of nuclear reactions. All of the actinide elements are radioactive and, except for thorium and uranium, special equipment and shielded facilities are usually necessary for their ...
The modern periodic table has two rows of elements below the main body of the table. The actinides are the elements in the bottom of these two rows, while the top row is the lanthanide series. These two rows of elements are placed below the main table because they don't fit into the ...

Inspired by these electro-precipitation methods, our group has developed an innovative device called “ActiFind” combining the electrochemistry of a thin synthetic layer of conductive boron-doped diamond (BDD), coupled with the radiometric detector made e.g., of silicon that now allows the direct...
Inner Transition Elements - The inner transition elements are the group of elements that are in the two rows below the main section of the periodic table. Visit BYJUS to learn more about Inner Transition Elements.

involves the handling of mixtures of metal ions where major impurities are often neighboring elements in the periodic table. In most cases, the ratio between the valuable element and impurities is extremely high (a few μg diluted in multi-g targets), rendering purification very challenging, albei...

Transients amounts of protactinium and atoms of neptunium are produced from the radioactive decay of uranium and from transmutation reactions in uranium ores, respectively (Asprey 2012 ). The other actinides (curium, americium, etc.) are synthetic elements (Darling 2011 ). Na ......
