Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

Answer 2

${\huge{\fbox{\color{aqua}{Answer :-}}}}$

✏Isotopes can be defined as the variants of chemical elements that possess the same number of protons and electrons, but a different number of neutrons. ... For example, carbon-14, carbon-13, and carbon-12 are all isotopes of carbon.

✏Isotopes are versions of the same element. They have the same number of protons and electrons as the element but different mass numbers and number of neutrons.

✏Isotopes are atoms with the same number of protons but that have a different number of neutrons. Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, isotopes are elements with the same atomic number but different mass numbers.

✏Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties.
