ANSWER:Step 1 of 2
The elements with the same valence electrons have similar chemical and physical properties and are placed in the same group in the periodic table.
Astatine has similar physical properties to Iodine. It is a solid element with a metal like appearance. Down the group, The melting and boiling point increases for halogens.
The melting point and boiling points of Astatine is higher than Iodine.
