This seems pretty weird to me, since, if I'm not mistaken, the superscripts and the numbers in the isotope names (e.g. See The Discovery of Oxygen: Common Compounds: It forms bonds with almost every other element and results in oxidation. What would the symbol be for an oxygen atom that has been changed to a free radical by a bombarding alpha particle? The element symbol for oxygen is O and its atomic number is 8. To use electron affinities properly, it is essential to keep track of sign. The enthalpy of fusion is a function of the pressure at which that transformation takes place. While it's common to write nuclear symbols with the atomic mass—the sum of the number of protons and neutrons—as a superscript and atomic number (the number of protons) as a subscript, there's an easier way to indicate nuclear symbols. Uranium is an element often described using this shorthand notation. The chemical symbol for Oxygen is O. where X is any atom or molecule capable of being ionized, X+ is that atom or molecule with an electron removed (positive ion), and e− is the removed electron. Overall, it's the most abundant element on the earth's surface and the third most abundant in the universe after hydrogen and helium. 4 answers Hydrogen is an explosive gas, oxygen supports combustion, why, when adding 2 hydrogen atoms to 1 oxygen atom, is the result an inert liquid? X + e– → X– + energy        Affinity = – ∆H. Heat capacity is an extensive property of matter, meaning it is proportional to the size of the system. Isotope Mass / Da Half-life Mode of decay Nuclear spin Nuclear magnetic … It is an intensive property, which is mathematically defined as mass divided by volume: In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance. ... nuclear bombs. The intensive properties cv and cp are defined for pure, simple compressible substances as partial derivatives of the internal energy u(T, v) and enthalpy h(T, p), respectively: where the subscripts v and p denote the variables held fixed during differentiation. Note that, these points are associated with the standard atmospheric pressure. Moreover: For example, sodium requires only 496 kJ/mol or 5.14 eV/atom to ionize it.
