Lanthanum - Element, Symbol, Chemical Properties, Uses

Lanthanum element or rare-earth metal symbol, chemical properties, uses, facts and found on periodic table. Discovery and production process f block La

Lanthanum (La) is the chemical element or rare-earth metal of Group 3 of the periodic table with atomic number 57 and valence shell electronic configuration [Xe] 5d1 6s2 4f0. The name rare earth was given because they originally extracted from rare earth oxide. It was first discovered by the Swedish chemist Carl Gustaf Mosander in 1839 and the name of lanthanum was given from the Ancient Greek latter lanthanein which means to lie hidden. It is the first f block element and prototype of the lanthanide family.

What are the f block elements in the periodic table?

The f-block elements in the periodic table appear in two series characterized by the filling of 4f and 5f sublevel in the respective third inner principal quantum number from outermost.

The 4f block in the periodic table has been variously called rare earth, lanthanum’s, and lanthanum. The lanthanum atoms and their trivalent ions have the following general electron configuration.

The second series f block elements result from the filling of 5f-orbital and consist of elements thorium to lawrencium with atomic number 90 to 103.

All of them are radioactive but most abundant radioactive isotopes of thorium and uranium have very long half-lives.
