WebMar 1, 2024 · An oxygen atom has 8 electrons. This is because the atomic number of oxygen is 8, which means it has 8 protons in its nucleus, and in a neutral atom, the number of electrons is equal to the number of protons. 3. Electronic Configuration of Oxygen The electronic configuration of oxygen is: 1s 2 2s 2 2p 4 Oxygen-18, 18 O; General; Symbol: 18 O: Names: oxygen-18, 18O, O-18, Ω, Heavy oxygen: Protons (Z) 8: Neutrons (N) 10: Nuclide data; Natural abundance: 0.2%: Half-life (t 1/2) stable: Isotope mass: 17.9991610 Da: Spin: 0: Isotopes of oxygen Complete table of nuclides See more Oxygen-18 ( O, Ω ) is a natural, stable isotope of oxygen and one of the environmental isotopes. O is an important precursor for the production of fluorodeoxyglucose (FDG) used in See more Fluorine-18 is usually produced by irradiation of O-enriched water (H2 O) with high-energy (about 18 MeV) protons prepared in a cyclotron or a linear accelerator, yielding an aqueous solution of F fluoride. This solution is then used for rapid synthesis of a See more In ice cores, mainly Arctic and Antarctic, the ratio of O to O (known as δ O) can be used to determine the temperature of precipitation through time. Assuming that atmospheric … See more In the study of plants' photorespiration, the labeling of atmosphere by oxygen-18 allows us to measure the oxygen uptake by the photorespiration pathway.
