... with protons and neutrons makes up atoms and molecules. An electron is a negatively charged particle. Atom: This is the smallest component of a chemical element. An Electrolysis Solution: An example of electrolysis is the splitting of CuSO4 via electricity, as shown on the diagram on the following page. A Voltage is applied to the electrodes with a power pack; this pushes the electrons to the negative electrode. The electrons get pushed into the cathode, after doing so the cathode becomes more negatively charged. The cathode begins to attract the positive copper (Cu) ions. The copper ions take electrons from the cathode to become neutrally charged copper atoms. The anode is positively charged; the anode then attracts the chloride ions. The chloride ions give up their extra electrons to the anode. The chloride ions then become chlorine molecules, the extra electrons that have been given up by the chlorine ions can then flow ...
