    Answer:

    It contains 20 neutrons

    It has an atomic number of 17.

    Explanation:

    According to this question involving chlorine atom (Cl), the mass number (A) is said to be 37. The mass number of an element is calculated by adding the proton number and the neutron number i.e.

    Mass no. = Proton no. + Neutron no.

    The proton number is also called atomic number, and in this case as it is on the periodic table, the atomic number of Chlorine is 17. This means that chlorine atom has 17 protons. To calculate the number of neutrons in 37Cl, we say:

    neutron no. = 37 – 17

    neutron no = 20

    From the above calculation, the following are true of 37 Cl:

    – It contains 20 neutrons

    – It has an atomic number of 17.
