Elements in group 17 of the Periodic Table are known as the halogens. The halogens include fluorine, chlorine, bromine, iodine, and astatine. These elements are very reactive because of their electron configuration, which is one electron short of a more stable nobel gas configuration.

Astatine wouldn't form salt as readily as other elements in Group 17. Astatine is a radioactive metalloid. Other elements in Group 17 are nonmetals.
The answer is Group 17 Halogens.
Its Halogen or something else. If it is Halogen then It is defined as : any of the elements fluorine, chlorine, bromine, iodine, and astatine, occupying group VIIA (17) of the periodic table. They are reactive non-metallic elements which form strongly acidic compounds with hydrogen from which simple salts can be made.
If by state the questioner means solid, liquid, gas then the answer is solid- Te is a silvery white metal. Its a trend in the main group elements (other than 17) that the heavier members of the group are metallic.
The most reactive family of nonmetals is the halogen family.
