JEE Main Chemistry question

Which statement is not true for astatine?

(A)It is less electronegative than iodine
(B)It exhibits only the oxidation stateCorrect
(C)Intermolecular forces between astatine molecules will be larger than between iodine molecules
(D)It is composed of diatomic molecules

Answer: (B)

Solution

Being below iodine in the group, astatine is expected to be less electronegative (A, true) and to have stronger intermolecular forces than iodine owing to its larger, more polarizable atoms (C, true); it is generally treated as composed of diatomic molecules like
