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.

What is the rarest naturally occurring element?
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.
What is the halogen in period 6?
The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.
What two Earth regions is oxygen the second most abundant element by volume?
The two Earth regions where oxygen is the second most abundant element by volume are the Earth's crust, after silicon, and the Earth's atmosphere, after nitrogen.
What is the second most abundant element in the universe but it is quite rare on earth?
Helium is the second most abundant element in the universe, but it is quite rare on Earth. This is because helium is a light and non-reactive gas that easily escapes Earth's atmosphere into space.
What is the second most common element after oxygen?
The second most common element after oxygen is silicon.
What is the rarest element on earth?
The rarest naturally occurring element on Earth is astatine. It is a radioactive element with a very short half-life, making it extremely rare and difficult to study. It is estimated that there is only a few grams of astatine present in the Earth's crust at any given time.
What is the rarest gas element in the earth's atmosphere?
The rarest gas element in Earth's atmosphere is neon, which makes up only a very small fraction of the atmosphere. Neon is present at a concentration of about 18 parts per million by volume.
What is the rarest single element in the earth's crust?
Iodine is one of the rarest elements in the Earth's crust, with an average abundance of about 0.47 parts per million.
What is the rarest naturally occurring element?
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.
What is the less common element on earth?
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.
What is a rare earth element in the lanthenide series?
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.
What is Second most common element?
The second most common element on Earth is silicon, which makes up about 28% of Earth's crust. The most common element found on a Earth is oxygen which is about 47%.
What is the most rarest element in the world?
astatine(less than 25g of it is present on earth acc. to guiness world records)
What is the halogen in period 6?
The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.
What is the rarest object on the 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.
What is the second most common element on Earth?
The second most common element on Earth is silicon, after oxygen. Silicon is a non-metallic element that is abundant in Earth's crust, mostly found in the form of silicon dioxide (silica) in rocks and minerals.
Why is astatine is the rarest element on the earth?
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.
