Jan 10, 2017 · $\ce O$ is a free oxygen atom and $\ce{O2}$ is two oxygen atoms chemically bound to form an oxygen molecule. There is no common analogy for $\ce C$, but $\ce{N2}$ is …

Nov 25, 2018 · Likewise $\ce{O2}$ 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 $\ce{O2}$ …

Feb 16, 2018 · Oxygen (O2) generally exists as diradicals i.e. each oxygen bonded to each other through single bonds and the remaining two electrons remains on each oxygen atoms as …

May 30, 2017 · $\begingroup$ The 2 O represents two separate oxygen atoms, ( not connected to one another so free to move around and react independently ), the $\ce{O2}$ is molecular …

Jul 18, 2014 · This phenomenon is explained by s-p mixing. All the elements in the second period before oxygen have the difference in energy between the 2s and 2p orbital small enough, so …

Jan 20, 2019 · $$\ce{2H2 + O2 -> 2H2O} \quad \Delta H = \pu{-466 kJ/mol}$$ This point is addressed in the Wikipedia page for "bond dissociation energy", the reference cited therein …

Feb 18, 2023 · O2-: Two electrons are added there is more inter-electronic repulsion, so the radius increases (and it is more than F-, because here two electrons are added but in F- only …

It's there in every high-school textbook: $\ce{O2}$ is the supporter of combustion. Without $\ce{O2}$ combustion cannot take place. Why? And why only $\ce{O2}$? Why not some other …

Feb 19, 2021 · So why is molecular oxygen $\ce{O2}$ more stable than the molecular ion $\ce{O2^2+}?$ One possible reason that comes to mind is that the antibonding (AB) orbitals, …

Jul 5, 2019 · The size of an anion is greater compared to its parent atom because former's effective nuclear charge is lesser than that of latter. I found on wikipedia that the effective …
