Electron Configuration Of Oxygen Ion

Electron configuration and oxidation states of oxygen.

Electron configuration of oxygen ion. Electron configuration of oxygen is he 2s2 2p4. With 10 electrons you should note that oxygen s electron configuration is now exactly the same as neon s. Oxygen is a chemical element with atomic number 8 which means there are 8 protons and 8 electrons in the atomic structure. An electron shell is the set of allowed states that share the same principal quantum number n the number before the letter in the orbital label that electrons may occupy.

For example we know that oxygen always forms 2 ions when it makes an ion. Electron configuration was first conceived under the bohr model of the atom and it is still common to speak of shells and subshells despite the advances in understanding of the quantum mechanical nature of electrons. Possible oxidation states are 2. Oxygen has six valence outer shell electrons and therefore gains two more electrons to form the o 2 ion.
