(a) Iodine is a lustrous non-metal. (b) Bromine is a non-metal which exists as a liquid at room temperature. (c) Graphite is the allotropic form of carbon and it is a good conductor of electricity. (d) Carbon is a non-metal which is known to form t
Q1: Give the physical and chemical properties of metals and non-metals. Answer: The following are some of the physical properties of metals: Nature is lustrous (shiny). Metal is an excellent heat and electrical conductor. The melting point and density are both high. Ductile Mouldable (Malleable...
One of the members may be conductive with the soldering glass coated thereon, or the soldering glass may be coated on a conductive element which becomes bonded between the pair of members.Eizo GotoUSUS4066427 * 1977年3月14日 1978年1月3日 Tokyo Shibaura Electric Co., Ltd. Metal nonconductor...
Definition of Non-Metal Non-metals are natural elements which do not have metallic properties. Often, they are available in the solid or gaseous state. In this type of elements, bromine is an exception as it exists in liquid state. They are good insulators of electricity and heat, non-lustr...
The metals are a good conductor of heat andelectricityas they can pass through them. They are good conductors of heat and electricity. The best conductors of electricity are silver and copper, however, lead and mercury are poor conductors of electricity.They also have a high melting point excep...

Q.9. Assertion (A): Iron is the most widely used metal.But it is never used in its pure state. Reason (R): Pure iron is very soft and stretches easily when hot. Q.10. Assertion (A): All non metals are insulators. Reason (R): Graphite is a good conductor of electricity...
A process for applying a principal metal coating to a non-conductive substrate without employing an electroless coating is disclosed comprising: (a) contacting the substrate with a suspension com
As an application of the fluctuation theorem, the analysis of the counting statistics gives the relation between the nonlinear transport coefficient and noise in quantum transport of a mesoscopic conductor38. Let I be the current and V the voltage between the electrodes. The nonlinear I–V ...
He presented an analytic solution and also showed that Ag/water is a good conductor of heat transfer. Sulochana and Naramgiri [16] considered the stagnation point flow of water-based copper nanoparticles along an exponential and horizontal movable cylinder with heat absorption/generation. Rekha et ...
