Isotopes are atoms containing the same number of protons but a different number of neutrons in their nucleus. Most of us are familiar with unstable isotopes (e.g., Carbon-14) which decay to another element (e.g., Carbon-14 decays to Nitrogen-14). This chapter, however, is concerned ...
Every nucleus of a given element must contain the same number (Z) of protons, but these nuclei can contain different numbers of neutrons. Most hydrogen atoms have nuclei that consist of a single proton, but a small fraction (about 0.015 percent) of the hydrogen atoms that occur in Nature ...

Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, ...
Atomic Number (number of protons in the nucleus): 8 Atomic Symbol (on the Periodic Table of Elements): O Atomic Weight (average mass of the atom): 15.9994 Density: 0.001429 grams per cubic centimeter Phase at Room Temperature: Gas
Mass Number The sum of the number of protons and neutrons of an atomic nucleus. In other words, it's the sum of the number of nucleons in an atom. Relative Atomic Mass The ratio of the average mass per atom of an isotope to 1/12 the mass of a carbon-12 atom. Relative atomic mas...
Oxygen isotopes refer to different forms of oxygen atoms that have the same number of protons but different numbers of neutrons in their nuclei. They can be used to determine the geological origin of ancient glass materials. AI generated definition based on:Treatise on Geochemistry (Second Edition...

Isotopes are variations of atoms that are classified as belonging to the same element. As the element is determined by the number of protons in the nucleus, all isotopes of the same element will have the same number of protons but will differ in their number of neutrons....
