Question: What is the primary reason for the brittleness of certain materials? (2023)

Options:

Correct Answer: High atomic bonding energy

Exam Year: 2023

Solution:

Brittleness is primarily due to high atomic bonding energy, which prevents the material from deforming plastically.

What is the primary reason for the brittleness of certain materials? (2023)

Step 1: Understand what brittleness means. Brittleness is when a material breaks easily without bending or stretching.
Step 2: Learn about atomic bonding. Atoms in a material are held together by bonds, which can be strong or weak.
Step 3: Recognize that high atomic bonding energy means the bonds between atoms are very strong.
Step 4: Realize that strong bonds make it hard for the material to change shape (deform) when force is applied.
Step 5: Conclude that because the material cannot deform easily, it is more likely to break instead of bending, making it brittle.
