The person who gives a theory of ions is Michael Faraday. It’s around 1830. He describes the portions of molecules that move from anode to cathode or vice versa.
He discovered that certain substances when dissolved in water conduct an electric current. He also noticed that certain compounds decompose into their elements when an electric current is passed through the compound.
Faraday introduced the term ions – (or wanderer in Greek) to describe the chemical species passing though the solution. He also introduced the terms ‘anion’ and ‘cation’ for positive and negative ions and ‘anode’ and ‘cathode’ for positive and negative electrodes.
How, there were no fully explanation until 1884 where the Swedish scientist name Svante August Arrhenius described it in his doctoral thesis. Arrhenius reasoned that an ion is an atom carrying a positive or negative charged.
Svante Arrhenius’s proposal that molecules of electrolytes break up into charged ions in dilute solution, whether or not electric current is present.
Michael Faraday did his experimenting with electromagnetism in 1821 by demonstrating the conversion of electrical energy into motive force. Using his special “induction ring” He discovered “electromagnetic induction” or generation of electricity. This is the first electricity transformer.

History is about people in society, their actions and interactions, the beliefs and prejudices their pasts and presents. History is the science which investigates and then records past human activities as are definite in time and space, social in nature and socially significant. The word ‘History’ means learned, expert, and knowledgeable. The word history has the connotation of finding out by investigation or inquiry.
