The anode is the electrode where oxidation occurs in a chemical reaction. It's the site where electrons are lost.
This is a process that involves losing electrons. In other words, it's when our generous friend (the anode) gives away their stuff (electrons).
This is a conductor through which electricity enters or leaves an object, substance, or region. The anode and cathode are both types of electrodes.
A type of chemical reaction that involves a transfer of electrons between two species. Our generous friend (the anode) giving away their stuff (electrons) to another friend (the cathode) is part of this process.
