The answer is iron. Iron has an atomic number of 26. This means than iron has 26 protons in it's nucleus. However, not all iron atoms have the same number of neutrons. Most commonly iron has 30 neutrons, but it also has 3 other stable isotopes. The word stable is important here because unstable elements are radioactive.
