    When metal is attacked by chemical corrosion, it will start

    • Deep within the metal.

    • On the surface of the metal.

    • Throughout the metal all at once.

    • Just under the surface of the metal.

    Correct Answer
    A. On the surface of the metal.
    Explanation
    When metal is attacked by chemical corrosion, it will start on the surface of the metal. This is because corrosion is a surface phenomenon where the metal reacts with the surrounding environment, such as oxygen or moisture, to form corrosion products. These products form a layer on the surface of the metal, gradually eating away at it and causing the corrosion to spread deeper into the metal over time. Therefore, the initial attack of chemical corrosion occurs on the surface of the metal.
