What is the difference between O O2 - Chemistry Stack Exchange $\ce O$ 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 called nitrogen, $\ce{H2}$ is hydrogen and $\ce{Cl2}$ is chlorine, each having the same name as that of their constituent elements
How does O2- have the largest radius - Chemistry Stack Exchange 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 one electron was added) In these questions where we compare the radius of isoelectronic species, i e species with same number of electrons, we compare the ratio of Nuclear charge (Z) to the number of electrons(e) ratio
Whats the difference between 2O and O2 [duplicate] $\begingroup$ 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 oxygen $\endgroup$ – porphyrin
Why is oxygen an oxidizing agent? - Chemistry Stack Exchange 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 radicals So this structural feature makes oxygen act as a strong oxidizing agent
