    May 30, 2017 · 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!

  3. Why do we call O2 oxygen? - Chemistry Stack Exchange

    Nov 25, 2018 · But why do we call O2 oxygen is my question? I thought only an atom with 8 protons can be called oxygen?

  4. orbitals - What is the origin of the differences between the MO …

    Jul 18, 2014 · S-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 …

  5. Why is oxygen more stable than oxygen dication?

    Feb 19, 2021 · According to molecular orbital theory (MOT), OX2X2+ O X 2 X 2 + has a greater bond order than OX2 O X 2 and two less antibonding electrons. So why is molecular oxygen …

  6. Why is oxygen paramagnetic? - Chemistry Stack Exchange

    May 3, 2016 · 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 …
