What does this mean- Most of the rare earth elements are considered to be synthetic?
All the rare earth elements are natural chemical elements (including prometium - element obtained also artificialy).
How many valance electrons do rare earth metals have?
16.546 valence electrons are located in all rare earth elements.
How are rare earth elements mined?
plants air and insecets all around the world ther are these things water plants and earth
Is arsenic rare?
Not really. It's about as common as the rare earths (which, despite the name, are not actually all that rare). On average, the Earth's crust is about 2 parts per million arsenic.
What elements do the earth sun and moon have in common?
All elements that occur in nature occur on Earth, the Sun, and the Moon - but the proportions are different. The main difference is that the Sun is made up mainly of hydrogen and helium; both are relatively scarce on Earth and on the Moon.
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.

What is lathanides?
Lanthanides?ærefers to the series of chemical elements that comprise the fifteen metallic chemical elements with atomic number 57 through 71. These elements are known as the rare earth elements.

What do elements 43 61 93-109 have in common?
All of these elements are synthetic. They are not found on Earth in nature, but are all created in nuclear labs.

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.
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.
