II. Isotopes Atoms of a given element all have the same number of protons and electrons, but can have different numbers of neutrons. Versions of the same element with differing numbers of neutrons are call isotopes. The symbol for an isotope is AX Where: A is the mass number (number of protons plus neutrons) Z is the atomic number (number of protons) X is the symbol for the element 2. Show the isotope symbol for the isotope of Fe with...
