The term 'PARTICLE IN AN ELECTROLYTE' can be summarized as an ION, which is a three-letter word. An ION is an atom or molecule that has gained or lost one or more electrons, giving it a net electric charge. Ions are important components of electrolytes, which are solutions that conduct electricity. Electrolytes are found in cells and other biological systems, and they are also used in industrial processes such as electroplating.
