What is an Isotope?

1. An Isotope is a form of element with same atomic number: each of two or more forms of a chemical element with the same atomic number but different numbers of neutrons. Isotopes of a given element share the same number of protons.  The number of protons  uniquely defines the element.
2. The nuclei of most atoms contain neutrons as well as protons. (An exception is the common form of hydrogen, whose nucleus consists of a lone proton). Every chemical element has more than one isotope. For any element, one of the isotopes is more abundant in
