Origin:
???????/lanthano(= to be hidden, to escape notice) .
The element called lanthanum because it is ?hidden? in rare minerals.

The name lanthana,that was first given to the new element, was suggested by Swedish chemist and his friend Jons Jacob Berzelius in 1817 ((1779-1848). Mosander announced the discovery of another rare earth contained in it that he named ?didymium? because it seemed to be ?an inseparable twin brother of lanthanum?.
Definition
Lanthanum is a chemical element wit atomic number 57 and atomic mass 138.90547. It is a moderately toxic element with soft silvery-white appearance. It is used in nickel metal hydrite (NiMH)rechargeable batteries for hybrid automobiles.
