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 an element.
No. Metal sulfides are generally insoluble, unless the metal is in group 1, like sodium.
No, that is 2 elements. One element would be Sodium (Na) and another would be Chlorine (Cl). Sodium Chloride would be a compound element.
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.
Yes, sodium bromide conducts electricity in the molten state because the ions are free to move and carry electric charge.
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
When sodium sulfide and cadmium nitrate are mixed, a double displacement reaction occurs. The sodium from sodium sulfide switches places with the cadmium from cadmium nitrate to form sodium nitrate and cadmium sulfide. Cadmium sulfide is a yellow solid that precipitates out of the solution.
because water conducts electricity
Cadmium does react with oxygen, acids, and the halogens. The acids it reacts with is sulfuric acid. Cadmium does react with water.
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.
Yes, sodium conducts electricity. It is a metal that can easily lose its outer electron to form a positive ion, allowing it to conduct electricity in both solid and molten states.
