    Answer:

    A negative charge

    Explanation:

    If there is an excess of electrons in a substance, this will have a negative net charge. This is because electrons have negative charge

    q = -1.67*10^{-19}

    each electron will contribute with this charge to the total negative net charge of the substance.

    hence, the answer is “A negative charge”
