Vedclass · Answer

(D) Option $A$ is correct as $Li$ and $Mg$ show a diagonal relationship due to similar ionic potential.Option $B$ is correct as $s$-block and $p$-block elements (excluding noble gases) are called representative elements.Option $C$ is correct as the $5^{th}$ period involves filling of $5s, 4d,$ and $5p$ orbitals.Option $D$ is incorrect because the general configuration for $f$-block elements is $(n-2)f^{1-14} (n-1)d^{0-1} ns^2$ where $n=6$ for lanthanoids $(4f)$ and $n=7$ for actinoids $(5f)$. The statement as written is technically correct in its general form,but often students confuse the $n$ value. However,looking at the options,all statements are factually correct. Re-evaluating: The question asks for the incorrect statement. Upon review,all provided statements are scientifically accurate. If forced to choose,there is no incorrect statement among the options provided.
