d and f BLOCK ELEMENTS MCQ Quiz: GKFix - Bridge of Knowledge

Question 1811

▼

According to the text, what is the general trend for the number of electrons involved in bonding as you move from left to right across a transition metal series?

It steadily decreases.
It remains constant.
It steadily increases.
It generally increases to a maximum around the middle and then may decrease.

Question 1812

▼

Which property is NOT listed as a typical metallic property of transition elements in the provided text?

High tensile strength
Ductility
High ionisation enthalpy
Metallic lustre

Question 1813

▼

What is the likely reason for the high enthalpies of atomisation observed in transition metals?

Weak interatomic forces exist in the solid.
They readily form gaseous atoms.
Their atoms are very small.
Strong cohesive forces in the solid lattice require significant energy to overcome.

Question 1814

▼

Based on the exceptions mentioned (Zn, Cd, Hg), what general characteristic do these metals share that differentiates them from other transition metals?

They are all liquids at room temperature.
They have empty d subshells.
They lack d electrons entirely.
They have filled d subshells in their common oxidation states.

Question 1815

▼

How does the high thermal conductivity of transition metals relate to their electronic structure?

Their large atomic masses facilitate heat transfer.
Their ionic bonds vibrate strongly.
Their tightly bound electrons prevent heat flow.
Mobile electrons efficiently transfer kinetic energy (heat) through the lattice.
