Ionic bond and covalent bond(electrolysis)

Molten Ionic bonding can be electrolysis to decompose to the original elements.

However , why can't the covalent bonding use the same method to decompose to the original elements.

    Firstly, it's not "molten ionic bonding". It should be the molten ionic compuond which is being electrolysed. You know, the wordings actually can cause deduction of marks in exams, so you should be careful with that. The bonding cannot be molten.

    And what you're asking is actually the concept of electrolysis. Electrolysis is based on oxidation and reduction of the elemetns (mainly metals). That is forming ions from an element/losing electrons (oxidizing) and gaining electrons (reducing). And covalent compound forms by sharing electrons and it belongs to neither any of the above. That's why covalent compound cannot be decomposed by electrolysis.

    What's more, in order to complete the circuit to run the electrolysis, the electrodes that you use should be conducting electricity and the solution/ molten copound (electrolyte) should be able to decomposed to give free electrons and ions to complete the circuit and to promote oxidation and reduction.
