WebWhy are some isotopes radioactive and some stable? These are radioactive isotopes, since they have an unstable atomic nucleus (due to the balance between neutrons and protons) and emit energy and particles when it changes to a more stable form.

WebA significant difference in the mean 13 C of kimberlites from different localities is indicated. For those kimberlite locations where he differences between their mean δ 13 C and δ 18 0 values are too great to be explained by a "combined isotopic effect process", then an inhomogeneous source reservoir of carbon isotopes is inferred. 展开 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.
