I believe you ment to say 'which element conducts electricity Cadmium or Sodium?'
They both do. They are both metals.
Ionic compounds conduct electricity when dissolved. Sodium chloride is an example
Sodium carbonate is a salt. Like all salts, it is non-conductive in solid form, but it is conductive in liquid form. Since it is water soluble, an aqueous solution of sodium carbonate also conducts electricity.
Sodium is a compound.
Sodium is an element.
No. Metal sulfides are generally insoluble, unless the metal is in group 1, like sodium.
sodium
In solution.
Sodium Chloride solution (dissolved in water) conducts electricity, and molten Sodium Chloride conducts electricty, but dry crystal Sodium Chloride does not conduct electricity.
Sodium chloride when dissolved in water forms an electrolyte that conducts electricity.
no?
Sodium Bromide
Sodium chloride solution conducts electricity through its bulk by motion of the oppositely charged sodium and chloride ions in it in opposite directions. At the electrodes used to measure conductivity, these ions interchange their electrons with the electrodes.
Ionic compounds conduct electricity when dissolved. Sodium chloride is an example
because water conducts electricity
Sodium bromide is an ionic substance. It conducts electricity when melted or when dissolved in water. This is due to the sodium, Na+ ions and the Br- ions present. It does not conduct electricity in the solid state as the ions can not move.
Sodium carbonate is a salt. Like all salts, it is nonconductive in solid form, but it is conductive in liquid form. Since it is water soluble, an aqueous solution of sodium carbonate also conducts electricity.
Interesting question. I suppose that Sodium Chloride is a solid substance in it's normal state, as mined in many parts of the world.(common table salt) Mercury is considered to be a metal, and conducts electricity extremely well. Perhaps that is what you were wondering. Perhaps you think it is NOT a metal. I think sodium conducts electricity and is used in Sodium Vapor lights which you often see in city streets. These are just my thoughts . See what others have to say.
