The transition metal having highest $3^{\text {rd }}$ ionisation enthalpy is :
$\mathrm{Cr}$
$\mathrm{Mn}$
$\mathrm{V}$
$\mathrm{Fe}$
Explain the variations in atomic radii of transition elements in group.
Identify the alloy containing a non-metal as a constituent in it.
Technetium, the element below manganese in the Periodic Table, would be expected to have high values for its
$(I)$ melting point $(II)$ boiling point $(III)$ density
Which is not true for transition elements
The spin only magnetic moments (in $BM$) for free $\mathrm{Ti}^{3+}, \mathrm{V}^{2+}$ and $\mathrm{Sc}^{3+}$ ions respectively are (At.No. $Sc: 21; Ti : 22; V : 23)$
