Answer: It has more neutrons. Its mass number is larger than the atomic mass number for carbon.
Step-by-step explanation:
We can see that all the isotopes of Carbon occupies the same slot in the periodic table and thus the same periodic number.
Atomic number of carbon = 6
Periodic Table gives us the information of Atomic number and mass number of atoms of an element.
Atomic number does not give any information about the number of neutrons of an atom. Atomic number of an element is the number of protons in the nucleus of each atom of that element.
Mass number is defined as the total number of protons and neutrons in an atom. Mass number of a typical carbon atom is equal to 12.
Isotopes are variants of a particular chemical element which differ in number of neutrons. Hence, the mass number of different isotopes of the same element varies and gives us information about the number of neutrons present in that atom at the same time.
The mass number of Carbon-14 is equal to 14.
Atomic number of C-14 = Protons in Carbon-14 = 6
Neutrons in Carbon-14 = Mass Number - Atomic Number
Neutrons in C-14 = 14-6
= 8
