    48

    Explanation:

    So all we have to consider here is the atomic number. Remember that in a neutral atom the amount of electrons = the amount of protons.

    Also that the atomic number = the number of protons.

    So we can say that in an atom with atomic number 48, there are 48 protons and therefore 48 electrons.
