Why do some substances conduct electricity and some not? Some are mode of uncharged particles called molecules. Sugar is such a substance. When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. Some substances that are made of molecules form solutions that do conduct electricity.
Why do some materials conduct electricity and some don t? In many materials, the electrons are tightly bound to the atoms. … Because these atoms are so reluctant to share electrons, these materials can’t conduct electricity very well, if at all. These materials are electrical insulators. Most metals, however, have electrons that can detach from their atoms and zip around.
Why do certain substances conduct electricity? Materials conduct electricity if one of two things happens: If electrons can move around freely (as in the delocalized bonds of metals), then electricity can be conducted. If ions can move around freely, electricity can be conducted.
Why are some substances conductive while others are not? Conductors are substances that allow electricity to pass through them freely. The reason behind this is that these substances contain many atoms that have loosely bound outermost electrons or valence electrons.
