Uranium is a metal and is a good conductor of both heat and electricity. The thermal conductivity and electrical resistivity of uranium are 27 W/m and 28.10-8 ohm.m respectively. In case of metals, a good conductor of heat is also a good conductor of electricity. This is not true for most of the nonmetallic substances. For instance, Diamond is a much better conductor of heat than copper, but it is an electrical insulator.
Copper is a good conductor of heat and electricity. The metal possesses numerous free electrons. These free electrons can easily nudge with the electrons around them. This results in the generation of electric current. Copper is not only a good conductor, but also malleable and ductile. So, the metal is converted into thin wires and is encapsulated by a non conducting material to be used as media for passing electricity.
Titanium is also a good conductor of electricity. Comparatively, electrical conduction of this metal is not as good as that of the metals like copper or silver but, is much better when compared to semiconductors. So, it conducts electricity much more actively than semiconductors but, less than good conductors.
One may be surprised to know that soda is a good conductor of electricity. But it is true as the compounds of soda when mixed with water to dissolve, separate into individual ions. One should remember that ions are good conductors of electricity.
Potato is a very good conductor of electricity. It contains lots of fibers in it that enables it to conduct the electrical energy. The vegetable is actually a mixture of water, salt and starch. When a salt is dissolved in water, it releases ions. Ions are good conductors of electricity. So, potatoes are good conductors of electricity and they are mostly used for making batteries.
Lemon is a citrus fruit and so, its juice contains citric acid. Actually, citric acid furnishes ions. Ions are well known for good carriers of electricity. The type of ions present in citric acid is H+. So, lemons are good conductors of electricity.
Urine is a good conductor of electricity. It contains lot substances that conduct electricity. These are known to be called as electro-conductive substances. Urine contains various anions like HPO4 2-, Cl-, SO4 2- and cations like NH4+, Ca2+, K+, Na+. Anions are also called as acid ions. So, do not even think to pee on electric wires!!
Iron is a good conductor of electricity, but not as good as silver. Iron is a metal is very much prone to corrosion in an oxygen environment. Iron is a high density metal, but brittle. The atomic number for the metal in the periodic table is 26 and is a member of the first transition series.
Silver is a metal that is widely known to be used in making ornaments. It is both malleable and ductile. We should know that it is a good conductor of electricity. The atomic structure of the metal is such that it offers a very easy path for the electrons to flow. The motion of electrons results in the transfer of electric current.
Gold is a yellow metal, best known for a costly metal and widely used in the making of ornaments. Gold is not only a good conductor of electricity, but also a good conductor of heat. The metal reflects infrared radiations very strongly. Most often, gold is used as plating for connectors. The metal does not conduct electricity as much as that of silver or copper.
