What are interstitial compounds? Why are such compounds well known for transition
Transition metals are large in size and contain lots of interstitial sites. Transition elements can trap atoms of other elements (that have small atomic size), such as $H , C , N ,$ in the interstitial sites of their crystal lattices. The resulting compounds are called interstitial compounds.

Which of the following have highest melting point
In the series $Sc(Z = 21)$ to $Zn(Z = 30)$ , the enthalpy of atomization of _____ is the lowest
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)
Assertion : The free gaseous $Cr$ atom has six unpaired electrons
Reason : Half-filled s orbital has greater stability.
