Identify the correct order in which the covalent radius of the following elements increases (I) (II) (III)
View answer and explanation
Correct option: D

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.
