10 Examples of Electrical Conductors and Insulators
2019/11/24· Whether a substance conducts electricity is determined by how easily electrons move through it. Electrical conductivity is dependent on electron movement because protons and neutrons don''t move—they are bound to other protons and neutrons in atomic nuclei.
Graphite is a non - metal. But still it conducts ele …
Graphite is a non metal but still can conduct electricity because of the delocalised (free) electrons in its structure. This is because each carbon atom in graphite is bonded to only three other carbon atoms and its fourth valence electron is free.
