12
Carbon is the sixth element on the periodic table of elements, which tells you that it has six protons in its nucleus. The name of the specific isotope, carbon-12, references the total number of particles in its nucleus, which are also known as nucleons. Taking those 12, minus the six protons, gives us six neutrons in an atom of carbon-12. Carbon-14, another isotope of the element, has eight neutrons for the same reasons.
The correct answer to this quiz is 6.
