When the current is passed through an electrolytic solution the negative ion moves towards the

On passing electric current through the electrolyte cations move towards the cathode and anions move towards the anode.

On reaching their respective electrodes these ions loose their charge. On loosing their charge they get deposited on the electrode or discharged as a gas.

Hope this helps :)

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

where are the choice options?
