Worked practice questions
A wire can be drawn out of a metal because the metal is:
- brittle
- sonorous
- ductile
- malleable
Show answer and solution
Correct answer: C. ductile
Ductility = ability to be drawn into wires.
Malleability is for sheets, sonority is for ringing.
Which non-metal conducts electricity?
- sulfur
- graphite
- phosphorus
- oxygen
Show answer and solution
Correct answer: B. graphite
Graphite (a form of carbon) is the standard non-metal that conducts electricity — used in dry cells and pencil leads.
