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, ...
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...
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 ...
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
Before it was discovered and isolated, a number of scientists had recognized the existence of a substance with the properties of oxygen: In the early 1500s Leonardo da Vinci observed that a fraction of air is consumed in respiration and combustion.(3) ...

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...
