This may be confusing, especially in situations where lanthanum itself isn't considered a member of the group! Erbium:symbol er, atomic number 68 13. In pure form, they are bright, metallic, and silvery in appearance.

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

Cerium:symbol ce, atomic number 58 3. Apr 16, 2001 · lanthanum is a white, malleable metal; The most common oxidation state for most of these elements is +3, although +2 and +4 are also generally stable. It is the first member of the third series of transition metals, and the first of the rare earths.

Europium:symbol eu, atomic number 63 8.

The chemical, metallurgical, and physical behaviours of the rare earths are governed by the electron configuration of these elements.

Promethium:symbol pm, atomic number 61 6.

Because the lanthanides are all transition metals, these elements share common characteristics.

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

For instance, lanthanum, cerium, praseodymium, neodymium, and europium react with oxygen to form oxide coatings or tarnish after brief exposure to air.

Lutetium:symbol lu, atomic number 71 note that sometimes lanthanides are considered to be the elements followinglanthanum on the periodic table, making it a group of 14 elements.
