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

A$$I,II,III$$
Correct Answer
B$$I,II$$
C$$II,III$$
D$$I$$ only

Solution

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. This is because it experience greater effective nuclear charge, which results in stronger metallic bonding and higher density.
