The electron configuration of oxygen is [He]2s22p4.
The electrons configuration for O2- is [He]2s22p6.
The pseudo noble-gas electron configuration has the outer three orbitals filled, the s, p and d- s2p6d10 (18 electrons total) and so is fairly stable. Elements that attain this electron configuration are at the right side of the transition metals (d-block). Br-, I-, Se2-
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
Mg 2+ Has the same electron configuration as neon. Two electrons lost to do this.
The transition metals
Electron configuration for an atom is the distribution of electrons on atomic orbitals.

The electron configuration of oxygen is [He]2s22p4.
The arrangement of the electrons in an atom is known as its electron configuration.
The electron configuration of sulfur is [Ne) 3s2.3p4.
The electrons configuration for O2- is [He]2s22p6.
The stable ions of all the elements except the Transition metals, Actinide, and Lanthanide series (that is the d and f block elements) form stable ions that are isoelectronic to a nobel gas by gaining or losing electrons in order to achieve an s2 p6 stable octet. For example, sodium will lose one electron to have the same electron configuration as neon, while nitrogen will gain three electrons to become isoelectronic to neon.
