What types of substances would definitely be good conductors? Hydrogen would be a good conductor because of hydrogen bonding.

Ionic substances would be good conductors since they dissolve in water and form ions.

Large molecules would be good conductors since they have a larger surface area.

Covalent substances would be good conductors since they have strong bonds.

Oxides would be good conductors because they like to share electrons.

Ionic substances would be good conductors since they dissolve in water and form ions.

Explanation:

Conductors can be defined as those materials which can allow the electricity to flow through them. The conductors also allow the transmission of heat and light from one to another source. They conduct electricity by allowing the electrons to flow through them easily.

The ionic substances can be good conductors because these can be dissolved in water and they will produce ions. The positively-charged ions will be attracted towards the negative electrode whereas the negatively charged ions to the positive electrode.
