What is Isotopes?​

Answer 1

Answer:

Two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element, they are known as Isotopes..

Answer 2

Answer:

Isotopes: 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.
