When it is in molten state or in aqeous state, i.e, it is dissolved in water as a solute. Why don't libraries smell like bookstores? No, sodium (Na) is a conductor not a semi conductor. One way is to free ionic constituents of a metallic salt from their normally-solid crystalline matrix, via melting or hydrating The mobile ions can then support electrical conduction within the molten salt or within a hydrated solution. Sodium Chloride, which is also called as ‘common salt’, and its chemical formula is ‘NaCl’, can conduct electricity, but under certain conditions. Why is melted paraffin was allowed to drop a certain height and not just rub over the skin? Why is melted paraffin was allowed to drop a certain height and not just rub over the skin? How long was Margaret Thatcher Prime Minister? How will understanding of attitudes and predisposition enhance teaching? Ans. This can be seen in rubber-coated wires and cables. How long will the footprints on the moon last? At high temperatures large ion vibrations from thermal fluctuations may knock an electron out of a filled shell, upon which it becomes a conduction electron and contributes to the conductivity. salt water is a good conductor of electricity as it contains sodium and chloride ions to carry out current. How long will the footprints on the moon last? The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. Sodium chloride is thus an insulator with a very high resistivity. As a metal sodium is not an insulator. Is there a way to search all eBay sites for different countries at once? When did organ music become associated with baseball? What is the conflict of the story of sinigang? Asked by Wiki User. On the other hands, electrons are not free to flow in sodium chloride, and thus its an insulator. What are the disadvantages of primary group? Why don't libraries smell like bookstores? 1 2 3. Wiki User Answered . Is sodium a conductor or a insulator? Sodium enters an insulating state at pressures of around 1.8 million times normal atmospheric pressure (180 gigapascals). This is an ideal quality in many cases—strong insulators are often used to coat or provide a barrier between conductors to keep electric currents under control. All Rights Reserved. How long does a fresh turkey last in the refrigerator? When did organ music become associated with baseball? Is it ok to eat a frozen turkey with black spots on it? How long does a fresh turkey last in the refrigerator? Copyright © 2020 Multiply Media, LLC. BAA. For example, in materials held together by the metallic bond, electrons float loosely between the metal ions. Impure semi conductor material are called extrinsic semi conductor as there a small quantity of foreign particle is present. How do you put grass into a personification? What is the reflection of the story the mats by francisco arcellana? These electrons will be free to move if an electrical force is applied. Answer. T i O 3 behaves as conductor or insulator depending on temperature because of variation of energy gap between valence band and conduction band with the variation … What is the contribution of candido bartolome to gymnastics? What are the disadvantages of primary group? The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. 10 Electrical Insulators . What is the conflict of the story of sinigang? Its because of the excess free electrons they possess. What is the reflection of the story the mats by francisco arcellana? Electric charges do not flow freely through insulators. The thermal conductivity is 142 W/m.K and the electrical resistivity is 47,7 nΩ.m
