WebWhat is an Isotope? Isotopes are various forms of an element that have the same number of protons but a different number of neutrons. Some elements, such as carbon, potassium, and uranium, have multiple naturally-occurring isotopes. Isotopes are defined first by their element and then by the sum of the protons and neutrons present. Carbon-12 ... WebQuestion: 2 A stable nucleus of an element has a certain number of protons and neutrons. Some isotopes have nuclei that are stable.
