Vedclass · Answer

(A) Technetium $(Tc)$ is a transition metal located in the $5th$ period,directly below manganese $(Mn)$ in the Periodic Table. Transition metals in the $4d$ and $5d$ series generally exhibit higher melting points,boiling points,and densities compared to their $3d$ counterparts due to stronger metallic bonding resulting from increased effective nuclear charge and more extensive $d$-orbital participation. Therefore,technetium is expected to have high values for its melting point,boiling point,and density. Thus,the correct option is $A$.

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
