Lecture 2 - U of L Class Index
... An element is defined by its atomic number. Changing the number of protons in an atom (as in a nuclear reaction) changes the element. While atoms of the same element must have the same atomic number, they may have different mass numbers. If so, they are referred to as isotopes. Most elements have mo ...
