Astatine has 33 isotopes, all radioactive and consequently unstable, with short half lives (the most stable isotope has a half life of 8,1 hours); therefore it is more correct to indicate the Atomic Mass of each isotope.
For this see the link: http://en.wikipedia.org/wiki/Isotopes_of_astatine.

Why is melting point of astatine higher than chlorine?
Because astatine is a heavier halogen.
What is the boiling point of astatine?
The boiling point of astatine is 337 0C.
Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
melting point
What are the 2 halogens with the highest melting points?
Melting points increase with atomic weight for elemental halogens (the second-most right column in a periodic table). The heavier the atom, the harder to turn it into a liquid. The lightest halogens, such as Florine (F) and Chlorine (Cl) are gasses at room temperature, having "melted" and "boiled" at lower (colder) temperatures. The two heaviest halogens are Iodine (I) and Astatine (At). Astatine is very rare, but Iodine is common and is a solid at room temperature. The have the highest melting points of halogens. Remember, F down to At increase in melting points. F and Cl are gases, so they have low melting point. Br is a liquid, so it has a higher melting point. I and At are solids so it takes more heat to melt them.
