Lewis formulas are not normally written for compounds containing___________elements.
(i) s-block (ii) p-block
(iii) d-block (iv) f-block

Options

A. (ii), (iii), (iv)
B. (iii), (iv)
C. (ii), (iii)
D. (i), (ii), (iii)

Answer

B

Explanation

The Lewis structures are not normally written for compounds containing d-block and f-block elements because these elements utilize d or f orbitals (or both) in bonding as well as s and p orbitals. Thus, they can accommodate more than eight valence electrons.
