“Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move
Most of the samples with metallic properties contained metallic bonds. The exception was carbon. Carbon is a non-metal and therefore has covalent bonds. However, in this experiment, it exhibited metallic properties. Carbon in the form of graphite is the only non-metallic element that conducts ele...
(a) Sodium (b) Iodine (c ) Gallium (d) LeadName the following : (a) A metal which is preserved in kerosene (b) A lustrous coloured non-metal (c ) A metal which can melt while kept on palm (d) A metal which is poor conductor of heat.
In general, conductivity refers to the capacity of a substance to transmit electricity or heat. A good conductor allows the free flow of electricity since it offers little or no resistance to the flow of electrons, thus leading to high electricalcurrent. Typically, metals, metal alloys, electroly...
That’s because metal is a great conductor of electricity. (In fact, so is the human body, which is why you can sometimes pass the shock on to someone else.) The opposite of a conductor is an insulator, which impedes the flow of electrons from one material to another. Rubber is a gr...
