Metals are considered the good conductors of electricity because of presence of free electrons. Normally when we talk about the electrical conductivity, metals comes first in mind. Electrolytes: Some elements, such as sodium, potassium, and calcium, are electrolytes and can conduct electricity when they are dissolved in water or other solvents.Semimetals: Some semimetals, also known as metalloids, such as silicon and germanium, can also conduct electricity, but not as well as metals.Metals: Most metals, such as copper, aluminum, silver, and gold, are good conductors of electricity.What class of elements conduct electricityĮlements that belong to the following classes generally conduct electricity: Materials that are good conductors of electricity, such as metals, are used in the construction of electrical wires and other components in electrical circuits, while materials that are poor conductors, such as insulators, are used to protect people from electrical shocks and to prevent the unwanted flow of electricity in circuits. The electrical conductivity of a substance can be affected by various factors, such as its temperature, pressure, and chemical composition.Įlectrical conductivity is an important property of many materials and is often used to classify and characterize them. The conductivity coefficient is a measure of the ease with which a substance allows the flow of electric charge through it. It is usually expressed in terms of a substance’s conductivity coefficient, which is the reciprocal of its electrical resistivity. In chemistry, electrical conductivity is a measure of a substance’s ability to conduct electricity.
