Physical Property of Non-Metal - Conductivity
Physical Property of Non-Metal - Conductivity
Non- metals are generally poor conductors of heat as they lack free electrons. Diamond, which is good conductor of heat, is an exception.
Electrical conductivity of Non- metals: Non- metals are generally poor conductors of electricity because they do not have the free electrons which helps in the conduction of electricity . Graphite, which is a good conductor of electricity, is an exception. Nonmetals have 4,5,6,7,8 electrons in their outermost shell. These electrons are not free and hence they do not conduct electricity.
Non-Metals are Poor Conductors of Heat and Electricity. This means that non- metals do not allow heat and electricity to pass through them. For example, sulphur is a non-metal which does not conduct heat or electricity. Similarly, a piece of coal (which is mainly carbon non-metal) also does not conduct heat or electricity. Many of the non-metals are, in fact, very good insulators. There are, however, some exceptions. A form of the carbon element, diamond is a non-metal which is a good conductor of heat. And another form of carbon element, graphite is a non- metal which is a good conductor of electricity. Being a good conductor of electricity, graphite is used for making electrodes (as that in dry cells).

Students / Parents Reviews [10]
It has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice

10thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.

8thA marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.

7thMy experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
Hiya Gupta
8thOne of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
Aman Kumar Shrivastava
10thAbhyas Methodology is very good. It is based on according to student and each child manages accordingly to its properly. Methodology has improved the abilities of students to shine them in future.
