Question

Which of these is a

property of a metal sample?
A. The sample insulates against electrical conductivity.
B. The valence electrons are held tightly in place to their atoms.
C. The sample will have a very low melting point.
D. The sample will be malleable.

Answer 1

Answer: D

Explanation:

• A is incorrect as metals are good conductors as opposed to insulators
• B is incorrect as metals have a sea of delocalised electrons
• C is incorrect as whilst some metals have low melting points, the majority have high melting points
• D is correct as the layers of ions can slide over each other when a force is applied
