Electron Configuration Of Oxygen 2-. Zinc's full electron configuration is: The remaining four electrons will go in the 2p orbital.
So 2es in k shell, and 8 es in l shell. The electron configuration of the chemical element describes the ground state, i.e. Oxygen is a chemical element with atomic number 8 which means there are 8 protons and 8 electrons in the atomic structure.
Electron configuration of oxygen is [he] 2s2 2p4.
The diagram above omits the #σ_text(1s)# and the #σ_text(1s*)# orbitals. When the atom is in excited state, one or more electrons go to a higher energy state, so electron configuration of the excited atom is different. Oxygen's total electronic configuration is 1s22s22p4. The group 16 element in the second period.
