Write the electronic configurations of the given ions O2–.

Write the electronic configurations of the given ions O^2–.

Numerical

O^2– ion

The electronic configuration of 0 atom is 1s² 2s² 2p⁴.

A negative charge on the species indicates that two electrons are gained by it.

∴ Electronic configuration of O^2– ion = 1s² 2s² p⁶
