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

Question 1836

▼

What is the primary reason transition metals generally exhibit high tensile strength?

They have low atomic masses.
They form weak van der Waals forces.
They contain only s electrons in their bonding.
Extensive metallic bonding involving d and s electrons creates strong interatomic forces.

Question 1837

▼

Based on the information about lattice structures, what can be inferred about the general packing efficiency of transition metal structures?

They primarily adopt inefficient simple cubic structures.
They adopt structures with low packing efficiency like body-centred cubic.
They tend to adopt highly efficient close-packed structures like hcp and ccp.
Packing efficiency is not a significant factor in transition metal structures.

Question 1838

▼

Which element listed in the 3d series table adopts a cubic close-packed (ccp) structure?

Vanadium
Chromium
Iron
Nickel

Question 1839

▼

According to the text, what is a key characteristic of the bonding in transition metals that differentiates them from main group metals regarding melting points?

Transition metals form ionic bonds.
Transition metals form covalent bonds.
Main group metals have lower atomic numbers.
Greater involvement of inner d-shell electrons leading to stronger bonds.

Question 1840

▼

What is the primary reason transition metals are generally good conductors of heat?

Their large atomic masses facilitate heat transfer.
Their ionic nature allows for easy energy transfer.
Their tightly bound electrons vibrate strongly.
The delocalized electrons can transfer kinetic energy efficiently throughout the lattice.
