Astatine has a valency of 1, because it is in group 7 and is part of the halogens. They say the group number is the number of valence, but the valency can't be 7. So they do 8 (the number of total outer shells allowed) - the group number if it's above 4.
8 - 7 = 1.
And all the other halogens, in group 7 like fluorine, chlorine, bromine and iodine have a valence of 1.
All in all, Astatine has a valency of 1.
