    Lanthanide - Wikipedia

    The lanthanide or lanthanoid (/ˈlænθənɔɪd/) series of chemical elements comprises at least the 14 metallic chemical elements with atomic numbers 57–70, from lanthanum through ytterbium. In the periodic table, they fill the 4f orbitals. Lutetium (element 71) is also sometimes considered a … See more

    Here's a list of the 15 elements that are lanthanides, which run from atomic number 57 (lanthanum, or Ln) and 71 (lutetium, or Lu): Note that sometimes lanthanides are considered to be the elements following lanthanum on the periodic table, making it a group of 14 elements.
    The lanthanides are: All of the lanthanides are shiny, silver-colored transition metals. Like other transition metals, they form colored solutions, however, lanthanide solutions tend to be pale in color. The lanthanides tend to be soft metals that can be cut with a knife.
    The lanthanide series is the group of elements in which the 4f sublevel is being filled. All of these elements are metals (specifically, transition metals ). They share several common properties. However, there is some dispute over exactly where the lanthanides begin and end.
    Lanthanides are all metals with reactivity similar to group 2 elements. Actinides are all radioactive elements. Lanthanides are used in optical devices (night vision goggles), petroleum refining, and alloys. Actinides are found primarily in applications where their radioactivity can be used to power devices such as cardiac pacemakers.
