In general this element has high melting points and boiling points. The lanthanides are the chemical elements found in Row 6 of the periodic table between Groups 3 and 4. They follow lanthanum (La), element #57, which accounts for their family name. The lanthanides include the metals cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), and lutetium (Lu).

Se hela listan på courses.lumenlearning.com Download Citation | The Lanthanides, Rare Earth Metals | The lanthanides (or lanthanons) are a group of 15 elements of atomic numbers from 57 through 71 in which scandium (atomic number 21) and The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. The lanthanides are the elements with atomic numbers from 57 to 71. These 15 metals (along with scandium and yttrium) are often called the rare earth elements. They are all silvery-white metals which are often found in the same ores. “Lanthanides” may not be a household name, but chances are they are part of your everyday life. These 15 elements which make up the bulk of the “rare earth metals” are not actually all that rare in parts of Asia, Australia, Africa and the Americas, but as they tend to occur together, they are difficult to separate from one another and obtain in pure form.

Are lanthanides metals

Lanthanides are used in optical devices (night vision goggles), petroleum refining, and alloys. The lanthanides are the elements with atomic numbers from 57 to 71. These 15 metals (along with scandium and yttrium) are often called the rare earth elements. They are all silvery-white metals which are often found in the same ores. The Lanthanides are rare earth elements of the modern periodic table.

The Lanthanides can also be used for ceramic purposes. The lanthanides are some of the largest non-radioactive metals in the periodic table.
