In an electrochemical cell, the electrode at which reduction occurs is called the

Explanation:
Reduction means gaining electrons, so the electrode where that electron gain happens is called the cathode. In a cell, electrons flow from the other electrode (the anode) through the external circuit toward the cathode, delivering electrons to the species that is reduced. In galvanic cells the cathode is the positive electrode, while in electrolytic cells it is negative, but in both cases the cathode is defined by being the site of reduction. The anode is where oxidation occurs, half-reactions describe the oxidation and reduction processes, and nuclear decay is not involved in electrochemistry.
