Copper, zinc and silver
The transition metals exhibit higher enthalpies of atomisation due to
Why $\mathrm{E}^{\circ}$ values for $\mathrm{Mn}, \mathrm{Ni}$ and $\mathrm{Zn}$ are more negative than expected?
Among $Co ^{3+}, Ti ^{2+}, V ^{2+}$ and $Cr ^{2+}$ ions, one if used as a reagent cannot liberate $H _{2}$ from dilute mineral acid solution, its spin-only magnetic moment in gaseous state is $......B.M$. (Nearest integer)
Transition element makes complex compound due to
If spin only magnetic moment of $VCl_X$ is $1.73\,BM$ then correct formula is
