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

Why the transition elements are hard and have high melting and boiling points?

How would you account for the following:

$(i)$ of the $d^{4}$ species, $Cr ^{2+}$ is strongly reducing while manganese $(III)$ is strongly oxidising.

$(ii)$ Cobalt $(II)$ is stable in aqueous solution but in the presence of complexing reagents it is easily oxidised.

$(iii)$ The $d^{1}$ configuration is very unstable in ions.
