Can non-metal conduct electricity? If yes, how? If no, why?

Non-metals are elements that generally do not conduct electricity. Properties of non-metals include a relatively low boiling point, which explains why many of them are gases at room temperature. An electric current is a flow of electrons. Elements that readily give up electrons (the metals) can carry electric current because their electrons can flow freely. Elements that gain electrons instead of giving them up cannot carry electric current. They hold onto their electrons so they cannot flow. Some non-metals are very reactive.The free electrons in the outer shells of the metal atoms form in the form of a cloud of gas. These free electrons conduct electricity through the metallic wires
