Which statement is most likely to be true for astatine, which is below iodine in Group VII of the Periodic Table? A Astatine and aqueous potassium chloride react to form aqueous potassium astatide and chlorine. B Potassium astatide and hot dilute sulphuric acid react to form white fumes of only hydrogen astatide. C Silver astatide reacts with dilute aqueous ammonia in excess to form a solution of a soluble complex. D Sodium astatide and hot concentrated sulphuric acid react to form astatine

A is not right because Astatine cannot displace chlorine as it is below chlorine in seventh group umm thats all i got

Just reviewed my notes and it says AgCl ios soluble, AgBr sparingly soluble and AgI is insolouble in NH3 by following the pattern silver Astatide must be insoluble ion dilute nh3 C is wrong
