Answer
Nucleus of the isotope $^{14}C$ will consist of 6 protons and 8 neutrons.
Work Step by Step
Position of element in the periodic table tells about the number of proton present in the nucleus of the atom. Since carbon is sixth element of the periodic table it will have 6 number of protons. Superscript in upper left of isotope element symbol denotes the mass number which is sum of number of protons and number of neutrons.
mass number = number of protons + number of neutrons
14 = 6 + number of neutrons
number of neutrons= 8.
