In the earth Astatine is rarest naturally occurring element, less than 30 grams for entire crust.
The rarest element is astatine. It is an unstable radioactive elment. It is a semi-liquid.
The rarest element on Earth is astatine.
Xenon is the rarest gas element in the earth's atmosphere. It represents 90 parts-per-billion of the total atmosphere.
The earth element ''Astatine'' which there is only 30-40gram of on the whole entire earth.
Of the following Elements;O,Si,Al,Fe,Ca,Na,K,Mg....which is the rarest single element in the Earth's crust?.....i say it's Mg because it is on 2% by weight of the Earth's crust.
Nitrogen is the least abundant element in the atmosphere of the Earth. The most abundant element in the atmosphere of the Earth is oxygen.
The 21st most abundant element in the Earth's crust is Chlorine (Cl). It forms 0.05% of the Earth's crust.
Xenon is the rarest gas element in the earth's atmosphere. It represents 90 parts-per-billion of the total atmosphere.
The second rarest element on Earth is unstable so it does not have a long life (22min.), but uranium is the rarest natural element and is the second heavist natural element. Actually, there are even rarer elements that last for less then fractions of a second. Some are so rare that they haven't even been discovered.
The earth element ''Astatine'' which there is only 30-40gram of on the whole entire earth.
Of the following Elements;O,Si,Al,Fe,Ca,Na,K,Mg....which is the rarest single element in the Earth's crust?.....i say it's Mg because it is on 2% by weight of the Earth's crust.
The rarest element on earth is astatine and it is located in the earths crust. Astatine's availability is said to be less than a gram in weight.
astatine(less than 25g of it is present on earth acc. to guiness world records)

Astatine is the rarest naturally occuring element on Earth because all its isotopes are radioactive with very short half-lives. The most stable, At-210 has a half-life of 8 hours, so any astatine that forms (by radioactive decay of heavier elements) quickly decays to other elements.
The rarest element in the world is astatine, and it costs $1 billion per troy ounce.
Astatine
oxegen
Nowhere. Francium is the second rarest element in the Earth's crust, next to Astatine. There is only 20-30g of it in the Earth's crust at any one time.
