these are f_block elements.most of f block compounds are ionic in nature.

The electron configuration of Astatine (As) is [Ar]4s24p3. The empty 4d orbitals can participate in the bonding to go beyond 3, to AsFr5. The type of bond, since the electronegativity difference is somewhat in the middle (relative to ionic and covalent bonding), is polar covalent bond.

FrAs would be a polarised ionic bond, due to the very large size of the As- ion.
