3Carbon exists in several different forms (called
allotropes)-diamond, graphite, soot,
charcoal Diamond is the hardest natural
substance. Thousands of tiny diamonds are
attached to saws and drills for cutting concrete
and drilling into rocks.
4This gas is an unreactive element. It does not
combine readily with other elements.Hence it can
be used in the packing of food It is also used
in the making of fertilisers.
5Sulphur is a yellow non-metallic element, found
in the free state. It is used to harden rubber
used for making tyres. It is also used in the
manufacture of sulphuric acid, pesticides and
drugs.
6Iodine is a non-metallic element that sublimes
when heated to form a violet vapour. When
dissolved in ethanol, it forms tincture of
iodine, used as an antiseptic.
7Oxygen is the most important gaseous element to
all living organisms on earth They need it for
respiration.
8Zinc is used to coat iron sheets to make
galvanised iron. It is also mixed with copper to
form the alloy, brass.
9Mercury is the only metallic element that is a
liquid at room temperature. It is used in
liquid-in-glass thermometers, fluorescent lamps
and some dental fillings
10Magnesium burns with a white dazzling light and
so it is used in distress flares. It is also
used in making fireworks.
11Aluminium, being strong, and of low density is
used to make aeroplane parts. This metal is also
used to make drink cans, cooking utensils and
ladders. Being a good electrical conductor and
of low density, it is also used to make overhead
electricity cables.
12This metal is commonly used to make electrical
wires as it is a good electrical conductor and is
inexpensive. It is also used to make water
pipes. When mixed with tin, it forms the alloy
called bronze and when mixed with zinc, it forms
the alloy called brass.
