An element is a pure substance that cannot be broken down into simpler substances by chemical means.
Descartes had a dualist substance theory and believed that there were two substances, the mind and the body. Locke also believed that there were spiritual substances and physical substances, but his theory of substance relied on the substratum, a characterless thing that contains the characteristics we observe. Since we cannot observe substance, Locke believed we could not know anything about it.

Good Insulator are those substance which has almost no free electrons to move freely and thus, cannot conduct electricity. When EMF (Electro motive force) is applied along the length of the insulator, high resistance of the insulator causes no motion of the electrons due to which the electrons cannot flow.
