Vedclass · Accepted Answer

$5d$ series is comprised of all elements from $La(Z=57)$ to $Hg(Z=80)$.

Vedclass · Answer

(C) The $5d$ series of transition elements includes elements from $Z=72$ $(Hf)$ to $Z=80$ $(Hg)$.Lanthanum ($La$,$Z=57$) is a $d$-block element but is often considered the start of the lanthanide series.The statement in option $C$ is false because the $5d$ series does not include all elements from $La$ to $Hg$ as a continuous transition series,and the range provided is inaccurate regarding the definition of the $5d$ transition series.
