Metals, by definition, are good conductors of electricity because of the large number of valence electrons which are free to move in an 'electron sea' around the metal lattice. As such, there are no...
Its a poor conductor because it has a tetrahedral lattice. Meaning that each one of its electrons are being used in bonding. Unlike other metals with 'sea's of free electrons' that can be used to...
Pure fresh water is a very bad conductor of electricity because there are very few ions in water. Salt water, on the other hand, is a good conductor, because the positive sodium ions and the negative...
