It is usually considered a metalloid, but also sometimes considered a halogen or just a plain ol' metal.
Astatine is a member of the group 17 (halogens) of the periodic table of Mendeleev: F, Cl, Br, I, At.
It is diatomic. Most textbooks will omit this, since astatine's chemistry is irrelevant to anything besides nuclear medicine.
No. it isn't. Astatine belongs to halogen family.
Yes, astatine is a member of the halogens family, after F, Cl, Br, I.
Astatine is a halogen (group 17, period 6).
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.
It is diatomic. Being radioactive, and its most stable isotope having a half life of 8.3 hours, it is usually not considered.
There are 2 atoms which make up a single molecule of a halogen. Fluorine, Chlorine, Bromine, Iodine and Astatine all exist as X2 , or diatomic molecules.

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.
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.
