In the earth Astatine is rarest naturally occurring element, less than 30 grams for entire crust.
Xenon is the rarest gas element in the earth's atmosphere. It represents 90 parts-per-billion of the total atmosphere.
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.
One of the rarest objects on Earth is the red diamond due to its unique coloration and limited supply. These diamonds are highly sought after by collectors and can fetch millions of dollars at auctions. Additionally, some meteorites, such as those from Mars or the moon, are also extremely rare and valuable.
Nitrogen is the least abundant element in the atmosphere of the Earth. The most abundant element in the atmosphere of the Earth is oxygen.
Yes, gold is a natural element found on Earth.
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.

Astatine is considered the rarest naturally occurring element on Earth. It is extremely radioactive and is typically only found in trace amounts in uranium and thorium ores.
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.
Promethium is the rarest naturally occurring rare earth element in the lanthanide series. It is radioactive and not found in significant quantities in the Earth's crust, making it one of the least abundant elements on Earth.
astatine(less than 25g of it is present on earth acc. to guiness world records)
The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.
One of the rarest objects on Earth is the red diamond due to its unique coloration and limited supply. These diamonds are highly sought after by collectors and can fetch millions of dollars at auctions. Additionally, some meteorites, such as those from Mars or the moon, are also extremely rare and valuable.
The rarest element in the world is astatine, and it costs $1 billion per troy ounce.
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.
