What is the difference between O & O2 - Chemistry Stack Exchange
Jan 9, 2017 · The common confusion here is that two very different things have the same name. O is a free oxygen atom and 2 O X 2 is two oxygen atoms chemically bound to form an oxygen molecule. …
Oxygen in water: How is it single if it's always double?
Mar 7, 2014 · Free single oxygen atoms are unstable and will bind to another free single oxygen atom that is present in the air because this is more stable. (So you get $\ce {O2}$) When you look at …
Why do we call O2 oxygen? - Chemistry Stack Exchange
Nov 25, 2018 · I have been taught that oxygen is a chemical element, in other words a certain type of atom that has 8 protons in its nucleus. So why is O2 called oxygen? It is not a type of atom but rather …
Effective nuclear charge of oxygen atom (O) vs oxygen anion (O2-)
Jul 5, 2019 · 0 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 nuclear charge can …
How does O2- have the largest radius - Chemistry Stack Exchange
Feb 18, 2023 · Na+: An electron is removed, so there is more effective nuclear charge, and pulls electrons towards nucleus, so again radius decreases. O2-: Two electrons are added there is more …
stability - Why is O2 a biradical? - Chemistry Stack Exchange
Also oxygen when it is single bonded to only 1 atom has 3 lone pairs of electrons making there be 7 electrons around it (and thus a -1 charge). I am assuming electrons are shared equally with half …
Why is the first ionization enthalpy of molecular O2 less than atomic O?
Sep 17, 2020 · If the molecules and their cations had the same bond length, and the electrons in a species didn't "talk to each other", and the orbital energies of an isolated atom were not influenced by …
Why is oxygen more stable than oxygen dication?
Feb 19, 2021 · According to molecular orbital theory (MOT), $\\ce{O2^2+}$ has a greater bond order than $\\ce{O2}$ and two less antibonding electrons. So why is molecular oxygen $\\ce{O2}$ more …
Whats the difference between 2O and O2 [duplicate]
May 30, 2017 · I just saw something in a chemistry lesson what got me confused. What is the difference between 2O 2 O and OX2 O X 2? Thanks for the help!
Oxidation states of oxygen - Chemistry Stack Exchange
Oct 15, 2016 · The concept of oxidation state simply works on concept of electronegativity.The more electronegative atom acquire a negative charge while less electronegative atom acquire a positive …
