Detailed explanation-1: -In simple terms, when you pass the current, cations move to the cathode side which is the negative terminal and take electrons it and then they get discharged into the neutral atom. If the neutral atom is solid, it gets deposited on the cathode and if it is gas, it moves upwards.

Detailed explanation-2: -The cathode is an electron donor and can cause reduction to occur. The negatively charged electrode will attract positive ions (cations) toward it from the solution. It can donate some of its excess electrons to such cations or to other species in the liquid being electrolyzed.

Detailed explanation-3: -The positive ions migrate toward the cathode (negatively charged) and the negative ions migrate towards the anode (positively charged); electrons flow from anode to cathode around the circuit.

Detailed explanation-4: -Positively charged ions move to the negative electrode (the cathode), and negatively charged ions move to the positive electrode (the anode). Ions are discharged at the electrodes producing elements. This process is called electrolysis.
