Rare earth elements are a group of 17 chemically similar metallic elements that exhibit unique magnetic, catalytic, and luminescent properties. They are typically found together in nature and share similarities in their electron configurations, making them difficult to separate from one another. Additionally, rare earth elements are essential components in many modern technologies, including electronics, renewable energy sources, and defense applications.

How many valance electrons do rare earth metals have?
16.546 valence electrons are located in all rare earth elements.
What does this mean- Most of the rare earth elements are considered to be synthetic?
This means that most rare earth elements are not found in nature in pure form but are instead produced through artificial processes. These synthetic rare earth elements are created through methods such as chemical reactions, nuclear processes, or extraction from mineral ores.
Is arsenic rare?
Arsenic is relatively common in the Earth's crust, but it is considered rare in its pure form. It is usually found in combination with other elements in minerals and ores. However, due to its toxic properties, it is not commonly used in everyday applications.
How are rare earth elements mined?
plants air and insecets all around the world ther are these things water plants and earth
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.
What are the uses of rare earth elements?
your TV, smart phone, car, head phones, speakers all use rare earth elements. there are many types of rare earth elements that all have different uses.

Are all rare earth elements radioactive?
All rare earth elements except promethium have at least one stable isotope.Natural-abundance samples of lanthanum, cerium, neodymium, samarium, europium, gadolinium, erbium, ytterbium, and lutetium are all technically "radioactive" in that they contain measurable amounts of radionuclides, but the half-lives of these nuclides are mostly in the hundreds of millions of years or longer (in some cases much longer).

Do scientists have to know all the chemical elements in the periodic table?
No. Firstly not all scientists are chemists. Secondly, not all chemists are working on problems that involve many of the elements. In fact only a small minority of working chemists could name the 15 lanthanide or rare earth elements. Thirdly, all chemists work with computer terminals or reference books nearby where they can easily look up rare or unfamiliar elements.
Is the Earth's atmosphere made up of all the elements on the periodic table of elements?
Not all of the elements are present in the Earth's atmosphere.

What elements is radioactive and synthetic barrium cesium currium and xenon?
Curium {Note correct spelling} is only element in the list given that is radioactive and synthetic.^ not correct answer and not even spelled right the correct answer is "lawrencium"The rare earth elements are located at the bottom of the periodic table and are comprised of the lanthanoid series and the actinoid series.The actinoid series is the second row of rare earth elements. All of these elements are radioactive, and all of these elements (except actinium, thorium, protactinium, and uranium) are synthetic.
