As pure elements, all of the halogens are diatomic molecular species. Their melting points are: F2, 85 K, C12, 239 K, Br2, 332 K, and 12, 457 K. Using the Periodic Table, predict as best you can the molecular formula of elemental astatine, At, the only radioactive element in this family. Also predict whether it will be a solid, liquid, or gas at room temperature. At2, solid O At2, gas O At, solid At2, liquid At, liquid O At, gas
