What is the difference between $\\ce{2O}$ and $\\ce{O2}$? Thanks for the help!Sun, 19 Apr 2026 08:32:00 GMThttps://chemistry.stackexchange.com/questions/14417/what-is-the-origin-of-the-differences-between-the-mo-schemes-of-o%e2%82%82-and-n%e2%82%82S-p mixing is the primary cause of the difference in the molecular orbitals of nitrogen and oxygen, which is influenced by the initial atomic orbital energies. The lighter second period elements (prior to oxygen) have a relatively small difference in energy between the 2s and 2p orbitals. This allows sufficient s-p mixing to lower the energy of the σ (2s) and σ* (2s) molecular orbitals, and ...Tue, 21 Apr 2026 21:29:00 GMThttps://chemistry.stackexchange.com/questions/104791/why-do-we-call-o2-oxygenLikewise $\ce {O2}$ is as much oxygen as atomic oxygen is. The only complication is that what we habitually think of as oxygen is oxygen as a gas comprised of $\ce {O2}$ molecules. Like Humpty Dumpty in Alice in Wonderland, "a word means what [we] choose it to mean" and often we have to add modifiers or alternate terms to avoid ambiguity.Mon, 20 Apr 2026 02:32:00 GMThttps://chemistry.stackexchange.com/questions/50600/why-is-oxygen-paramagneticParamagnetic molecules are molecules that have single electrons. When I draw the lewis structure of $\\ce{O2}$, it appears to be a diamagnetic structure. What makes it paramagnetic?Sat, 18 Apr 2026 15:06:00 GMThttps://chemistry.stackexchange.com/questions/169849/what-form-of-energy-is-produced-by-2h2-o2-2h2o-reaction0 Thermal energy is released from the reaction $\ce {2H2 + O2 -> 2H2O}$. Before the reaction takes place the system of $\ce {H2}$ and $\ce {O2}$ molecules are in a metastable state: Given enough energy > activation energy the system gains enough energy to overcome the potential barrier and falls into a state of lower energy than the initial state.Sat, 11 Apr 2026 08:12:00 GMThttps://chemistry.stackexchange.com/questions/15058/why-is-o2-a-biradicalAnd finally there is $\ce {O#O}$ where both oxygens are positively charged and are free radicals. Why are both positively charged? It is because 3 bonds already to oxygen means 1 lone pair and 5 electrons around oxygen is +1. Is it because of these resonance structures giving 2 free radicals in $\ce {O2}$ that $\ce {O2}$ is considered a biradical?Sun, 19 Apr 2026 12:06:00 GMThttps://chemistry.stackexchange.com/questions/188318/enthalpy-of-formation-of-o2The enthalpy of formation of O2 is zero at any particular temperature. The element is already in its ''standard state'' . Also please note that as per IUPAC, there is no standard temperature, it is only convention to use 298.15K to collect standard state data. Standard conditions as per IUPAC change depend upon what substance you are dealing with. For example, it is defined at standard ...Sun, 22 Mar 2026 10:45:00 GMThttps://chemistry.stackexchange.com/questions/160359/what-is-the-lumo-and-homo-in-and-o2-diatomicIn the typical way these terms are used, the LUMO can't be the same as the HOMO. Since each of the pi spatial orbitals already have one electron, they are not unoccupied, so they can't be the LUMO. In the sense of singly occupied spin orbitals, you could say that these pi spin orbitals are the LUMO, but its fairly nonstandard to refer to spin orbitals when discussing HOMO/LUMO.Wed, 25 Mar 2026 07:42:00 GMThttps://chemistry.stackexchange.com/questions/79083/what-is-the-nature-of-the-fe-o2-binding-in-oxymyoglobin-and-oxyhemoglobinOn the other hand, the $\ce {Fe (III)-O2-}$ binding scheme would be expected to have a temperature-dependent magnetic susceptibility, as antiferromagnetic coupling could be overcome with higher temperatures. In other words, there is a thermally accessible triplet state.Sat, 18 Apr 2026 13:48:00 GMT
