Lanthanides are called rare earth metals because they are not frequently found in concentrated deposits, making them less abundant than other metals. The name "rare earth" refers to the fact that these elements were initially believed to be rare when they were first discovered. However, they are actually more abundant than some other elements in the Earth's crust.

How many rare earth metals are there?
There are 17 rare earth metals, which include the 15 lanthanides, plus scandium and yttrium. These elements are known for their unique properties and are essential in various high-tech applications, including electronics, renewable energy technologies, and military equipment. Despite their name, rare earth metals are relatively abundant in the Earth's crust, but they are rarely found in economically exploitable concentrations.
What is the difference between rare metals and rare earth metals?
Rare metals are simply metals that aren't common. They don't necessarily have any chemical properties in common. (Many of them do, because they tend to cluster in certain regions of the periodic table - around iridium and rhodium.)Rare earth metals are, specifically, the lanthanides (scandium and yttrium are also sometimes included, because they tend to be found in the same mineral deposits where the lanthanides are found). They tend to be very similar chemically, to the point where it's actually difficult to separate them by their chemical properties.The rare earths are not really all that "rare": with the exception of promethium (which has no stable isotopes), they're considerably more common than the truly rare metals. Gadolinium is, for example, about a thousand times more common than gold.
Elements with atomic numbers of 58 through 71 are known as the?
Elements with atomic numbers of 58 through 71 are known as the lanthanides, a group of transition metals that have similar properties and are often found together in nature. They are commonly used in various applications such as magnets, catalysts, and electronic devices.
Why lanthnides are called rare earth metals?
Lanthanides are called rare earth metals because they were initially found in rare minerals, and they share similar chemical and physical properties. They are not actually rare in occurrence but are difficult to extract and purify, making them valuable and unique.
