The chemical symbol ln may be used to refer to any lanthanide in general, not specifically the element lanthanum.

Additionally, none of the elements occurs free in nature. Strontium and barium have much lower abundances. In pure form, they are bright, metallic, and silvery in appearance. These elements, plus lanthanum (element 57) and actinium (element 89), are known collectively as the rare earth elements or rare earth metals.

Lanthanides are reactive—readily forming ionic compounds with other elements.

Strontium and barium have much lower abundances.

Neodymium:symbol nd, atomic number 60 5.

Fifteen of the elements belong to the same series and are referred to as lanthanides while the other two, scandium and.

The iupac classify 17 elements with similar properties that are generally found within the same ore as rare earth elements.

Promethium:symbol pm, atomic number 61 6.

Praseodymium:symbol pr, atomic number 59 4.

Unlike other most other transition metals, the lanthanides tend to be soft, sometimes to the point where they can be cut with a knife.
