WebIn this post, I will explain why metals are such good electrical conductors, and also explain how nonmetals like water and glass can also become conductors. Metals conduct electricity because they have “free electrons.”. Unlike most other forms of matter, metallic bonding is unique because the electrons are not bound to a particular atom. WebAn electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move. Other materials— semiconductors and conductors —conduct electric current more easily. The property that distinguishes an insulator is its resistivity; insulators have higher ...
