6 protons & 7 neutrons.
The predominant isotope of Carbon is C-12 with 6 protons & 6 neutrons and Carbon-14 used in radiocarbon dating is 6 protons & 8 neutrons.

well the mass number=protons+neutrons. Carbon has 6 protons, so the equation is
13=6+neutrons, subtract 6 form each side
7=neutrons so there are 7 neutrons, 6 protons, and the electrons are not in the nucleus so they don;t count
I just now realized that you needed the number of subatomic particles... Not their specific types. Well the number of subatomic particles is always equal to the mass number.
