Match the given pair of elements with the corresponding relation between them.
Atoms of the same element having same number of protons but a different number of neutrons are called isotopes.
Atoms of different elements which have same mass number and different atomic number are called isobars.
Atoms having same number of neutrons but a different atomic number are called isotones.

126C and 146C have same number of protons but different number of neutrons. So, they are isotopes.
146C and 147N have same mass number. So, they are isobars.
146C and 168O have same number of neutrons. So, they are isotones.
