As an expert in the field of materials science, I can provide a detailed explanation regarding the conductivity of metals and other materials.
Metals are generally renowned for their ability to conduct electricity, and this is due to their atomic structure. In metals, the outer electrons, also known as valence electrons, are loosely bound to their respective atoms and are free to move throughout the metal lattice. This sea of delocalized electrons allows metals to conduct electricity efficiently. Metals like copper, aluminum, and silver are particularly good conductors and are commonly used in electrical wiring and various electronic devices.
However, it's important to understand that not all metals are created equal when it comes to conductivity. There are variations in the electrical conductivity of different metals, which can be influenced by factors such as purity, temperature, and the presence of impurities or defects in the metal's crystal lattice.
The statement "The opposite is not true" suggests that while metals are good conductors, not all good conductors are metals. This is accurate. There are indeed many non-metallic materials that exhibit good electrical conductivity. For instance, semiconductors, which are materials with electrical conductivity between that of a conductor and an insulator, can be engineered to have very high conductivity under certain conditions. They are crucial in the electronics industry for their ability to control and amplify electrical signals.
Additionally, there are conducting polymers, which, although not as conductive as metals like copper or aluminum, can be produced to have better conductivity than some metals when properly formulated. These polymers have the advantage of being lightweight and flexible, which can make them suitable for certain applications where traditional metals are not.
Graphene, a form of carbon, is another notable non-metallic conductor. It is a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice. Graphene has an impressively high electrical conductivity and is considered to be one of the best conductors known, surpassing even some metals.
In summary, while metals are typically excellent conductors of electricity due to their atomic structure, there are also non-metallic materials that can be good conductors. The electrical conductivity of a material is not solely determined by whether it is a metal or not; it is also influenced by its composition, structure, and the conditions under which it is used.

The opposite is not true. There are lot of good non-metallic conductors. Semiconductors may be very good conductors, there are conducting polymers (not as good as copper or aluminum but properly produced they should conduct better than some metals), graphene is a good conductor.Feb 28, 2012
