The electron configuration for an O2- ion is 1s22s22p6 just like the noble gas neon.
The element, oxygen, is in group 16, period 2 of the periodic table. Thus its electron configuration is 1s2 2s2 2p4. Oxide's ionic state is O2-, so to get its electron configuration we just need to add two electrons to the old one. That yields 1s2 2s2 2p6.
Oxide - O2- electronic configuration of oxygen atom: 1s2, 2s2 2p4. electronic configuration of oxygen ion: 1s2, 2s2 2p6. phosphate - PO43-
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
The electron configuration of oxygen is [He]2s22p4.
[He]2s^22p^6

Oxide ion O2- is isoelectronic with neon.
The electron configuration of oxygen is [He]2s22p4.
Ionic
The electrons configuration for O2- is [He]2s22p6.
Neon, if you are talking about an oxygen ion.
