Classify the elements based on their property of conductivity with suitable examples.
Answers
Answer:
All metals are known to be the best conductors. Their conductivity depends on the number of valence electrons of their atoms. ... Metals have such electrons in their atoms, and so they conduct heat and electricity so well. Metals allow the electric field to transmit through them in conductivities order of 106 – 108 ohm-1.
Explanation:
On the basis of conductivity ,the materials can be classified in to following categories:-
(a) Conductors:- These are those materials whose electrical conductivity is very high. Conductors conduct charges very easily . For super-conductor , the value of electrical conductivity is infinite.
Examples. Copper,Silver.Aluminum,Tungsten etc.
(b) Semiconductors:- They are those materials whose electrical conductivity lies in between insulators and conductors . Semiconductors can conduct charges but not so easily as in case of conductivity.
Examples. Germanium.Silicon etc.
(c) Insulators:- These are those materials whose electrical conductivity is either very very small or nil. Insulators do not conduct charges.
Examples. Glass,Rubber,Wood etc.
