Astatine is a solid at room temperature because of its intramolecular attraction. It is a chemical that is radioactive with a symbol of At and an atomic number of 85.
it is a SOLID,chemical element with the symbol At and atomic number 85. This radioactive element occurs naturally from uranium-235 and uranium-238 decay. It is the heaviest of the halogens.
At room temperature astatine is a solid halogen, nonmetal.
Technically it would be a solid; however, there is so little naturally-occurring astatine that for all practical purposes it doesn't exist in large enough quantities to even see with the unaided eye.
At room temperature astatine is a solid nonmetal.

Astatine is a solid at room temperature.
Astatine is a solid at 20 0C.
General classes of colloids are: gas in liquid, gas in solid, liquid in gas, liquid in liquid, liquid in solid, solid in gas, solid in liquid, solid in solid.
at 100oC fluorine, chlorine and bromine are gas. iodine and astatine are solid
evaporation solid to liquid - melting liquid to gas - evaporation gas to liquid - condensation liquid to solid - freezing solid to gas and gas to solid - sublimation
The liquid to gas phase change is vaporizing; the reverse is condensing. The other phase changes are: - solid to liquid: melting - liquid to solid: freezing - solid to gas: sublimation - gas to solid: deposition

Astatine is not a metalloid but a nonmetal; astatine is a solid because is more heavier than fluorine.
