Ionic substances conduct electricity when they are dissolved in water. Ionic substances release ions into water so that they carry electricity through the solution. Water containing dissolved ions is a very good conducto... More »

Semiconductors are substances that conduct electricity only under certain conditions. Germanium, Silicon and sometimes tin are types of semiconductors that occur naturally and do not require chemical doping to form cryst... More »

Water can easily conduct electricity if it contains ionic compounds, but pure water does not conduct electricity. Pure water is rarely found in nature, therefore the majority of water found on Earth does conduct electric... More » Science Physics Electricity

Ionic compounds conduct electricity when they are dissociated into positive and negative ions that are free to move. The larger the number of mobile positive and negative ions, the more conductive the ionic material beco... More » Science Physics Electricity

Graphite conducts electricity because it possesses delocalized electrons in its structure. The honeycomb layout of the stacked carbon atoms of graphite leaves a single electron unbound in each hexagon. Each of these elec... More »

Carbon graphite conducts electricity. Graphite, an allotrope of carbon, has free electrons what carry charges from one place to another throughout the graphite. This process causes electricity flow. More »

The element mercury conducts electricity. It can be used to construct position dependent switches that are silent. Manufacturers also use mercury in fluorescent lights and advertising signs. More »
