    Answer:

    20 electrons

    A neutral atom with atomic number 20 will have 20 electrons.

    The atomic number is, by definiton, the number of protons in an atom’s nucleus but for a neutral atom it’s also equal to the number of electrons. Each element has a different, unique number of protons that determines its identity.
