    Answer:

    The composition of a sodium ion is 11 protons 10 electrons an 12 neutrons

    Explanation:

    Sodium has one electron in its outermost shell. In addition to that, sodium ion is formed by the electrovalent  combination of sodium atom with another element. During this, the sodium atom loses an electron to become a positively charged sodium ion.

    This loss of an electron changes the number of electrons in the atom from 11 to 10. The proton number and mass number still remains 11 and 12 respectively since the combination only affects the electrons of the element.

    This imbalance between the proton number and electron number in the sodium ion is what makes it positively charged (Na^{+})

    Constituent summary of (Na^{+})

    Proton number: 11

    Neutron number: 12

    Electron number: 10
