- What is the difference between O O2 - Chemistry Stack Exchange
What is the difference between $\ce {O}$ and $\ce {O2}$ If C is carbon and then why $\ce {O2}$ is oxygen
- Whats the difference between 2O and O2 [duplicate]
I just saw something in a chemistry lesson what got me confused What is the difference between $\\ce{2O}$ and $\\ce{O2}$? Thanks for the help!
- stability - Why is O2 a biradical? - Chemistry Stack Exchange
And 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?
- Why is oxygen paramagnetic? - Chemistry Stack Exchange
Paramagnetic 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?
- orbitals - What is the origin of the differences between the MO schemes . . .
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 that s-p mixing (combination) can occur lowering the energy of the σ (2s) and σ* (2s) and increasing the energy of the σ (2p) and σ* (2p) molecular orbitals By moving towards right in a period, the s orbital gets more
- Why is O2 the supporter of combustion? - Chemistry Stack Exchange
The main benefit of oxygen is that its the most commonly available oxidizer The main component of air that support combustion is oxygen However titanium burns in nitrogen and so does lithium, and also some other active metals such as finely divided aluminium These form nitrides Similarly most of these active metals also burn in hydrogen forming hydrides such as lithium
- Why is oxygen more stable than oxygen dication?
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, although higher in energy than the constituent atomic orbitals, are still negative in energy, so adding electrons to AB orbitals still lowers the energy
- Why do we call O2 oxygen? - Chemistry Stack Exchange
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 $\ce {O2}$ 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
