possible

To Do:
 Complete the
Properties of
Metals worksheet
Lustrous
All metals are shiny when polished
or freshly cut
Flexible
Metals do not break – they bend
Ductile
Metals can be drawn into wires
Malleable
Metals can be hammered into sheets
Sonorous
Metals ring like a bell when hit - they
do not make a dull thud
Electrical conductor
Thermal conductor
All metals conduct electricity
Metals allow energy to flow through
them, causing heating

strong
magnetic
brittle
high melting point
hard
Which is the odd one out?
B
C

Cobalt
Copper
D
Copper is non-magnetic
– iron, cobalt and nickel
are magnetic
Nickel
Which is the odd one out?
A
Antimony
B
C
Palladium
Arsenic
D
Palladium is the only
metal – the others are
non-metals
Graphite
Which is the odd one out?
A
C
B
Iridium

Mercury is liquid at room
temperature – the others
are solids at room
temperature
D
Mercury
Which is the odd one out?
B
A
Aluminium
C
Bronze
D
Brass
Electrum
Aluminium is an element
– the others are mixtures
of two or more elements
Which is the odd one out?
A
B
Sodium
Potassium
D
Lithium
C
Calcium
Calcium is in Group 2 –
the others are in Group 1
of the Periodic Table
Which is the odd one out?
B
C
A
Silver
Tin

D
Tin is only found as a
compound – the others often
occur naturally as elements
Gold
Which is the odd one out?
A
B
Sonorous
D
Magnetic
C
Malleable
Good Thermal
Conductor
Only cobalt, nickel and iron
are magnetic – the others
are properties of most
metallic elements
Which is the odd one out?
B
C
A
Selenium
Calcium
Palladium
D
Selenium is a non-metal
– the others are metals
Zinc
Which is the odd one out?
B
C
A
Iron
Thallium
D
Magnesium
Zinc
Thallium is extremely toxic –
you need small quantities of
the others in your diet to
remain healthy
Which is the odd one out?
B
C
A
Molybdenum
Copper
D
Tungsten
Yttrium
Copper has been known
since ancient times – the

Write in full sentences
Metals are good thermal
conductors
Most metals have high
melting points
1. Saucepans are made of
copper, iron, steel or
aluminium
Metals are good electrical
conductors
Most metals are ductile...
... they can be drawn out into
wires
2. Electrical wires are made
of copper
Most metals are flexible
Most metals are flexible
3. Springs are usually
made of steel (an
alloy of iron)
Metals are lustrous...
... shiny when polished or freshly
cut
Most metals are ductile
4. A lot of jewellery is
made of gold
Most metals are malleable...
... they can be beaten flat into
sheets
Most metals are sonorous...
... they ring when hit, rather
than make a dull thud
5. Bells are made of bronze
(an alloy of copper and
tin) or brass (an alloy of
copper and zinc)
Most metals are strong
Because metals are flexible,
buildings with a metal frame
have some ‘give’ in them...
... meaning that they survive
better during earthquakes
6. The framework of
skyscrapers is made of
iron or steel girders
Iron and steel are much lighter
than brick or stone so metalframed buildings can be taller
than masonry buildings
Metals are good electrical
conductors
Most metals have a high melting
point
(The filament glows because it gets
very hot – 2000 to 3000 ˚C)
7. The filament in
light bulbs is
made of
tungsten
Most metals are hard
The harder the blade is, the less
quickly it goes blunt
8. Saw blades are
made of steel
Most metals are malleable...
... so the lead flashing can be
moulded to the contours
of the roof
9. Flashing – the joins
on roofs are
waterproofed with
sheets of lead
Most metals are NOT magnetic
Only iron, nickel and cobalt (and
their alloys) are magnetic
If we made the casing of a
compass from a magnetic metal it
would shield the compass needle
from the Earth’s magnetic field...
10. The casing on
compasses is
made of brass or
aluminium
... so the compass would not
work!
