    The simple way to remember this is
    "LOAN"
    L= LEFT
    O= OXIDATION
    A=ANODE
    N=NEGATIVE

    And the all opposite terms for cathode

    - During electrochemical corrosion, transfer of electrons takes place. Corrosion cell is formed due to electrons and ions produced due to corrosion reaction.

    - Corrosion cell exists only if it contains anode, cathode, metal path and electrolyte.

    - On anode, oxidation takes place and electrons are evolved. These electrons are consumed by the cathode and result in reduction reaction.

    - The flow of electrons from anode to cathode takes place through metal path.

    - Ionic current flows through the electrolyte. The products of oxidation and reduction are formed in this electrolyte.
