isotopes of an elements have the same number of protons but different number of neutrons. therefore, the mass numbers are different.
For example,
1H = 1p, 0n, 2H (deuterium) = 1p, 1n, 3H (tritium) = 1p, 2n

Atoms or elements are isotopes of one another if they have the same number of protons but different number of neutrons. Examples: H-1 and H-2 are stable isotopes of hydrogen. C-12 and C-13 are stable isotopes of carbon. Saying isotope is a little like saying twin or triplet, because a person is a twin or triplet by virtue of their relationships to other persons. Some elements like Co or Au are monoisotopic in nature, because they have only one stable isotope.

An Isotope is the same element with different no of neutons...
For example C-12 has 6 protons and 6 neutrons and C-14 has 6 protons and 8 neutron.
so they have sample symbol but different mass etc etc

Isotopes are different forms of an element each having different atomic mass. Isotopes of an element have nuclei with the same number of protons but different numbers of neutrons. Therefore, isotopes have different mass numbers, which give the total number of nucleons(the number of protons plus neutrons)
