Questions with solutions
Q1 — Physical & Chemical Properties · medium · theory
Metals can be beaten into thin sheets. This property is called:
A. malleability ✓ Correct
B. brittleness
C. sonority
D. ductility
Solution: Malleability is the ability to be hammered into sheets; ductility is being drawn into wires.
Q2 — Physical & Chemical Properties · medium · theory
Most metals are good conductors of:
A. sound only
B. heat and electricity ✓ Correct
C. neither heat nor electricity
D. only light
Solution: Metals conduct heat and electricity well due to free electrons.
Q3 — Physical & Chemical Properties · hard · theory
The only metal that is liquid at room temperature is:
A. iron
B. copper
C. mercury ✓ Correct
D. sodium
Solution: Mercury is the only metal that is liquid at ordinary temperatures.
Q4 — Physical & Chemical Properties · hard · theory
Which non-metal is a good conductor of electricity (an exception)?
A. Phosphorus
B. Sulphur
C. Graphite ✓ Correct
D. Iodine
Solution: Graphite, a form of carbon, conducts electricity although it is a non-metal.
Q5 — Physical & Chemical Properties · medium · theory
Non-metals in the solid state are generally:
A. malleable and shiny
B. good conductors
C. ductile
D. brittle and dull ✓ Correct
Solution: Solid non-metals are usually brittle, dull and poor conductors (with a few exceptions).
Q6 — Physical & Chemical Properties · hard · theory
The oxides of metals are generally ______, while the oxides of non-metals are generally ______:
A. neutral; acidic
B. basic; neutral
C. acidic; basic
D. basic; acidic ✓ Correct
Solution: Metal oxides are basic (e.g. Na₂O), whereas non-metal oxides are acidic (e.g. CO₂, SO₂).
Q7 — Physical & Chemical Properties · medium · theory
Metals produce a ringing sound when struck. This property is called:
A. sonority ✓ Correct
B. lustre
C. ductility
D. malleability
Solution: Sonority is the property of producing a ringing sound; that is why metals are used in bells.
Q8 — Physical & Chemical Properties · hard · theory
The hardest naturally occurring substance, which is a form of the non-metal carbon, is:
A. diamond ✓ Correct
B. graphite
C. iron
D. quartz
Solution: Diamond, an allotrope of carbon, is the hardest natural substance.
