Carbon-14 is an isotope of carbon. Isotopes of an element have same number of protons but different number of neutrons.
Atomic number of carbon is 6.
So, the number of protons = 6.
Atomic mass number for carbon-14 is 14.
Mass number = Number of protons + Number of neutrons
Therefore,
Number of neutrons = Mass number - Number of protons
=14 - 6 = 8
Thus, it has 8 neutrons and 6 protons.
