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?
