    Answer: 27 neutrons

    Explanation:

    Recall that the number of protons in the nucleus of an atom = Atomic number.

    Hence, Calcium with mass number 47 and atomic number 20 will have 20 protons

    Therefore, since Mass number = number of protons + neutrons

    47 = 20 + neutrons

    Neutrons = 47 - 20 = 27

    Thus, there are 27 neutrons in radioactive calcium nucleus.
