- (D) Because of its large molar mass (creating somewhat strong London
Dispersion Forces between iodine molecules), iodine exists in the solid
state at 25°C and 1 atmosphere of pressure. Elemental fluorine and chlorine
are gases under these conditions while bromine is a liquid. Due to heat
produced by its own radioactivity, a sample of elemental astatine has never
been viewed.
