Why are metal good conductor of electricity? This article will explain why metal are good conductor of electricity.

Metal valence electrons are not tightly dependent (because of their low ionization energy), so they are relatively free to move. It is understandable why metals are good conductors of heat and electricity, as well as shiny.

Conductivity is defined as the ease with which an electric charge or heat can pass through a metal. A conductor is a material or substance that can conduct electricity or heat (heat) well. On the other hand, an insulator is a material or substance that is difficult to conduct electricity and heat. Examples of ordinary conductors are metal objects such as iron, steel, copper, etc., while examples of insulators are wood, plastic, and rubber. Thermal conductivity refers to the ease with which heat passes through a conductor or insulator.

From the brief explanation, actually the question “why are metal good conductor of electricity” has been answered.

Why are Metal Good Conductor of Electricity

So, speaking about conductors, do you know which metals are the best conductors of electricity and heat? The conductivity of all metals is compared to that of silver. On a scale of zero to 100, where 100 is the most conductive, silver ranks 100.

Apart from being a strong conductor of electricity, silver does not make sparks easily. It is used in electrical components such as contacts and circuits. It is important to note that the gold level is 76 on the conductivity scale. Popular belief suggests that gold is a better conductor than silver, but facts prove this assumption to be incorrect.

Top 10 Metal for electricity Conductor

Beside the Quiz of “Why are metal good conductor of electricity?” Below the profiles of 10 metals, the best conductors of electricity and heat.

1. Silver

Silver is a metallic element with atomic number 47. Its symbol is Ag, reconstructed from the Latin argentum, from the PIE root, as * h2erǵ, “gray” or “shiny”. A soft, white, glossy transition metal with the highest electrical, thermal  and reflectance of any metal.

2. Copper

Copper is a chemical element in the periodic table, the symbol is Cu and the atomic number is 29. The symbol comes from  Latin copper. Copper is a good conductor of heat and electricity. In addition, this element exhibits very rapid corrosion. 

3. Gold

Gold is a chemical element in the periodic table, the symbol is Au (Latin: “aurum”) and the atomic number is 79. Transition metals (trivalent and monovalent) that are soft, shiny, yellow, heavy, “flexible” and “ductile” responsive. Gold reacts unaffected by other chemicals, but is attacked by chlorine, fluorine and aquaresia. This metal is widely distributed in gold lumps and powders of rocks and  alluvial deposits and is one of the monetary metals. The ISO code is XAU. Gold melts in the form of a liquid  at a temperature of about 1000 degrees Celsius. 

4. Aluminum

Aluminum is a good conductor of electricity. Light and strong. It is also a good heat conductor. It is forged into a sheet, stretched into wires and extruded into rods of various cross sections. Corrosion resistance.

5. Zinc

Zinc is the metal of the symbol Zn. Zinc has been used since at least the 10th century BC. second hand. Zinc metal is a bluish white metal that is shiny and diamagnetic. Zinc metal is a  hard and brittle metal at various temperatures and can be hammered at temperatures between 100 and 150 degrees Celsius. Zinc is also a better electrical conductor  than any other metal and  has a lower melting point than any other metal.

6. Nickel

Nickel is a metallic chemical element with the Ni symbol. Nickel is a metal that does not easily rust. Pure nickel is malleable, but when combined with iron, chromium and other metals, it can form hard, rust-resistant steel. 

7. Brass

Brass is an alloy of copper (Cu) and zinc (Zn). The comparison of copper and zinc depends on the characteristics of the brass you are trying to make. However, in general, the copper content is 60-90% of the total mass. 

8. Bronze

Bronze is a metal alloy containing copper (Cu) as the main component and other metals such as tin (Sn). In addition to tin, other miscible metals  are manganese (Mn), aluminum (Al), phosphorus (P) or silicon (Si). In general, bronze contains 88% copper and 12%  tin.

9. iron

Iron is a metal extracted from iron ore (mining) and is widely used in daily  life in the periodic table. The iron  symbol is Fe and the atomic number is 26. It also has  high economic value.  Iron is the most common metal and has the most versatile uses. This is due to several reasons: The generation of iron in the  crust is very high, its processing is relatively easy and inexpensive, and iron has beneficial properties and can be easily changed. One of the drawbacks of iron is that it is easily corroded.

10. Platinum

Platinum is a member of the Platinum Group and is an element of Group 10 of the Periodic Table. There are 6 natural isotopes. This metal is one of the rare elements in the Earth’s crust, with an average abundance of about 5 g / kg. It occurs in some nickel and copper ores and some natural deposits, especially in South Africa, which accounts for 80% of the world’s production. Due to its rarity in the  crust, its annual production is only a few hundred tonnes, providing significant benefits. This metal has become extremely valuable and is an important precious metal product. So I hope my article “10 Metals, the Best Conductors” will help you.

So, the answer of why are metal good conductor of electricity, is the metal valence electrons are not tightly dependent (because of their low ionization energy), so they are relatively free to move.
