Are non metals conductors or insulator give two examples of non metals that are conductors?
Non metals are generally poor conductors of electricity and heat, meaning they are insulators. However, there are a few non metals that can conduct electricity to some extent under certain conditions. Two examples of non metals that are conductors are:
1. Graphite: Although graphite is composed of carbon atoms, which is a non metal, it exhibits semi-conducting properties. It can conduct electricity along its planes due to the delocalization of electrons, making it a good conductor for low-voltage applications.
2. Selenium: Selenium is a non metal that can also conduct electricity, but it is a much poorer conductor compared to metals. It is often used in certain photocopiers and photovoltaic cells due to its photoconductivity properties.
Non-metals are generally poor conductors of electricity and are known as insulators. However, there are a few non-metals that can conduct electricity to some extent. Two examples of non-metals that can act as conductors are:
1. Graphite: Graphite is a form of carbon and is widely used as a conductor. It has a unique layered structure which allows the movement of electrons to occur easily along its surface. This property makes graphite a good conductor of electricity, although it is still not as efficient as most metals.
2. Graphene: Graphene is a single layer of graphite and is also made up of carbon atoms. It is an excellent conductor of electricity due to its unique structure, which allows electrons to move freely across its surface.
It is important to note that while these non-metals can conduct electricity, they are still considered as poor conductors compared to metals.
