Which of the given relations about the above elements are correct.
I) 12C
II) 14C
III) 14N
IV) 16O
I and II are isotopes
II and III are isobars
II and IV are isotones
Nuclei with the same number of protons but a different number of neutrons are called Isotopes.
Nuclei with the same number of neutrons but a different atomic number are called Isotones.

12C and 14C have same Proton number but different Neutron number so they are isotopes
14N and 14C have same mass number so they are isobars.
14C and 16O have same number of neutrons so they are isotones.
