Carbon-14 atom have 6 protons plus 8 neutrons.
Explanation
Carbon-12 and Carbon-14 are examples of isotopes of carbon that have huge applications in the field of science.
Isotopes are those elements who have equal number of protons and electrons whereas their neutrons differ.
Therefore isotopes have same atomic number, as atomic number depends on number of protons or number of electrons whereas number of neutrons do not have a role in atomic number.
But mass numbers of isotopes are different as mass numbers depend on the number of protons and number of electrons.
