The amount of energy released when atoms of iodine in vapour state are converted to ions is . What is the electron affinity of iodine in per atom?
View answer and explanation
Correct option: D
-3.06
Option D (-3.06) is correct because the electron affinity is calculated by dividing the total energy released by the number of atoms and converting the units to eV.

The elements with zero electron affinity are
S-I: paramagnetic.
S-II: All the orbitals present in ion are doubly occupied. Which of the following is the most electropositive element? The law of Octaves is not applicable to: Assertion (A): Mendeleev's arranged elements in horizontal rows and vertical columns.
Reason (R): Mendeleev's ignored the order of atomic weight thinking that the atomic measurements might be incorrect. Which of the following electronic configuration does not belong to same block as others?
