Due to the fact that the amount of astatine found in a whole kilometre of the earth's crust contains less than 50 mg of astatine, no accurate price can be made due to the fact that a very small of amount of an extremely radioactive material will be hard to make.
Astatine
Since astatine is a group 7 element I guess it is -1.
Astatine is an element in the periodic table, belonging to group 7.It has an atomic number of 85.
The element with the symbol At is Astatine. Astatine is a Group 17(7) Halogen and is radioactive. It has 85 electrons in 6 shells, with 7 electrons in the outer shell.
All the isotopes of astatine are radioactive and has very short half lives; consequently is a dangerous element.
Astatine is an element with the symbol At.
The color of the element astatine is unknown.
Astatine is not a mineral but a chemical element. Astatine can be obtained as a pure element but in extremely small quantities.
In the earth Astatine is rarest naturally occurring element, less than 30 grams for entire crust.
As a radioactive element with a short half life astatine is dangerous.
Astatine is produced by nuclear reactions.
The element with the atomic number 85 is Astatine (At). Astatine is a Radioactive Halogen in Group 17(7) of the Periodic Table. Astatine has 85 electrons in 6 shells with 7 electrons in the outer shell. Astatine is the third radioactive element on the Periodic Table.
Yes. There are no stable isotopes of astatine, they are all radioactive.
"Astatine is really rare. Attempt to find some if you dare."
The 85th element on the Periodic Table of Elements is astatine (At). It is a highly radioactive element and the heaviest known halogen. Astatine is rare and is primarily produced as a result of decay processes in uranium ores.
Astatine is similar to the halogen family
The rarest element in the world is astatine, and it costs $1 billion per troy ounce.
