The oxide ion O2- has the same electron configuration as neon?
yes.
No
To determine if the oxide ion (O2-) has the same electron configuration as neon, we first need to find the electron configuration of each species.
The electron configuration of an atom or ion describes how the electrons in its subshells are distributed. Neon (Ne) has an atomic number of 10. Therefore, its electron configuration is 1s^2 2s^2 2p^6.
Oxygen (O) has an atomic number of 8. The oxide ion (O2-) has gained two electrons compared to oxygen. Since oxygen has the electron configuration of 1s^2 2s^2 2p^4, the oxide ion can be represented as 1s^2 2s^2 2p^6.
Comparing the oxide ion's electron configuration (1s^2 2s^2 2p^6) to the electron configuration of neon (1s^2 2s^2 2p^6), we can see that they are indeed identical.
So, yes, the oxide ion O2- does have the same electron configuration as neon (Ne).
