Density of astatine
WebFluorine is the lightest element of Group 17 of the periodic table called halogens. This group includes chloride, bromine, iodine, and astatine. It has an atomic number of 9 and a density of 1.5127 g cm−3 at −188.13 °C. As with the other halogens, fluorine occurs as a diatomic molecule, F 2, in its elemental form. WebNov 21, 2024 · Density of Astatine. Density of Astatine is 6.4g/cm 3. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume. It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V
