Lanthanides are any of the series of 15 consecutive chemical elements in the Periodic Table from lanthanum to lutetium (atomic numbers 57 - 71). With scandium and yttrium, they make up the rare earth metals. Their atoms have similar configurations and similar physical and chemical behaviour; the most common valences are 3 and 4.
A lanthanide element is any element that resides in the Lanthanide series on the Periodic Table. The Lanthanide series is just under the Actinide series on the Periodic Table and is usually seperated from the main part of the Periodic Table. All of the Lanthanide elements are radioactive.
chemical element with the symbol La and atomic number 57, is the first element of the lanthanide series
Lanthanum is a metal element that is silvery-white. It has the atomic number of 57 and is a solid at room temperature. It is a rare earth element.
The set of chemically related elements with properties similar to those of lanthanum, with atomic numbers from 57 to 71; the rare-earth elements.
Lanthanam is used for carbon arc lighting. This rare element is used to make these lights that are used for projector and studio lights in the film industry.
Lanthanum is an element. It is made of lanthanum atoms.
A lanthanide is an element between lanthanum and lutetium in the periodic table, which have very similar properties.
They are called Lanthanoids or the Lanthanide Series.

The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
This chemical element is promethium (Pm).
It is an element - a lanthanide metal - with atomic number 69.
The smallest atomic number and atomic weight for a lanthanide is lanthanum itself, element 57. The smallest atomic size is lutecium element 71; the lanthanides steadily decrease in atomic radius through the series, and the smallest is the last of them.
They are called Lanthanoids or the Lanthanide Series.
