The elements X,Y,Z and T have the indicated electronic configuration. Starting with the innermost shell, which is the most metallic element?
View answer and explanation
Correct option: C
Z=2,8,8,1
Option C (Z=2,8,8,1) is correct because metallic character increases with the ease of losing electrons, and this configuration has only one valence electron, making it the most metallic.

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?
