Multiple Choice
Which of the following is a general physical property of metals?
A
They are usually brittle and break easily.
B
They are good conductors of electricity.
C
They are generally dull in appearance.
D
They have low melting points.
Verified step by step guidance1
Understand what a physical property is: a characteristic of a substance that can be observed or measured without changing its chemical identity.
Recall common physical properties of metals, such as luster (shine), malleability, ductility, electrical conductivity, and melting points.
Evaluate each option against typical metal properties: metals are usually not brittle but malleable, so 'brittle and break easily' is incorrect.
Consider electrical conductivity: metals are known to be good conductors of electricity, which is a key physical property.
Check the other options: metals are generally shiny (not dull) and tend to have high melting points, so those options are incorrect.
