Chemistry Changes Everything: ¹ᶟ¹I - Iodine¹ᶟ¹ An isotope is two or more forms of an element where the nuclei of the element has more neutrons than protons and normally each element only has one stable isotope of the element. Changing the neutrons in the atom also changes the atomic mass but not chemical properties. Radioisotopes are radioactive versions of an isotope where the atom or element has an unstable nuclei therefore emitting radiation. An unstable nuclei is created when there is either
