The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, ...

Key fact Isotopes are forms of an element that have ... neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.

My current research projects involve using stable nitrogen isotopes and cosmogenic nuclides to investigate North Atlantic ice sheet dynamics and ocean biogeochemical cycling across the Pleistocene.

A radioactive isotope's nucleus is unstable and spontaneously decays, giving off radiation and changing into a different isotope. The rate at which nuclei decay is constant. Half-life describes ...
