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 are lanthanide's called rare earth metals?
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.
Why were they named rare earth metals?
They were rare metals that are found in the earth.
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.

Where on the periodic table are the rare earth metals located?
The rare earth metals are located in the lanthanide series of the periodic table, which is found at the bottom of the table.
Is coltan part of rare earth metals?
No, coltan is not part of rare earth metals. Coltan is short for columbite-tantalite, which is a metallic ore that contains elements such as niobium and tantalum. Rare earth metals refer to a group of 17 elements on the periodic table.
What is the difference between galvanized and alkanized cells?
Alkalized cells use the alkali metal groups of the periodic table or the rare alkaline earth elements. Galvanized cells use any and all metals.
