Question

Read the following passage about metals.
Elements are divided into metals and non-metals. All metals are electrical conductors.
Many of them have a high density and they are usually ductile and malleable. All these
properties influence the way the metals are used. Some metals are sonorous and so
they are used for special purposes.
a) Explain the underlined terms?
b) Copper is ductile . How is this property useful in everyday life?
c) Aluminium is hammered and bent to make large structures for use in ships and
planes. What property allows it to be shaped like this?
d) Name one metal that has a low density?
e) Some metals are cast into bells. What property must the chosen metals have?
f) Complete the statement with correct words.
Metals are good conductors of _______ and _______.

Answer 1

b) coppers high ductility property is very useful for industrial purpose
c) aluminum is malleable. this allows it to bent
d)lithium has a very low density
e) when struck metals produce a sound called metallic sound or metallic clink .this property is used
f)metals are good conductors of heat and electricity....
a) elements can be classified to metals and non metals on the basis if their properties
characteristics of metals are
1) good conductors of heat and electricity
2) they have high density except few like lithium Mercury etc
3)they are ductile, malleable and sonorous
