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.
Why were they named rare earth metals?

How many electrons does rare earth metals have?
Rare earth metals have a varying number of electrons, as it depends on the specific element within the group. The rare earth metals are a group of elements in the lanthanide series of the periodic table. They typically have between 57 to 71 electrons based on their atomic number.
