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.
The electron configuration of thaliium III ion is [XE] 4f14 5d10.
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 a Copper(II)ion is [Ar]4s0 3d9.

Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The most likely electron configuration for a sodium ion in its ground state is 1s22s22p63s1.
It has 2 electrons in the first shell, and 8 in the second as it gains an electron to form an ion so the configuration is 2,8.
