Why can some covalent compounds conduct electricity?
Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.
Why electricity Cannot pass through covalent compounds?
Covalent compounds form when atoms that have similar electronegativity values form covalent chemical bonds. When a covalent compound dissolves in water, it does not dissociate into ions. Because there are no free electrons or ions in the water (electrolytes) dissolved covalent compounds can't conduct electricity.Oct 5, 2017
Why do some substances not conduct electricity?
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 ionic compounds conduct electricity and covalent compounds do not?
(a) Ionic compounds are made up of electrically charged ions. Thus, it conducts electricity whereas covalent compounds are made up of electrically neutral molecules. Thus, they do not conduct electricity.
