In this video we will write the electron configuration for O 2-, the Oxide ion. We’ll also look at why Oxygen forms a 2- ion and how the electron configurati 2019-08-03 2015-11-11 Electron Dot Diagrams. Recall that the valence electrons of an atom are the electrons located in the highest occupied principal energy level. Valence electrons are primarily responsible for the chemical properties of elements.

Ce (Z = 58 Note that when writing the electron configuration for an atom like Fe, the 3d is usually written before the 4s. Both of the configurations have the correct numbers of electrons in each orbital, it is just a matter of how the electronic configuration notation is written (here is an explanation why). Therefore we have 1s 2 2s 2 2p 6 3s 2 3p 6 3d The electron configuration of the chemical element describes the ground state, i.e. the state in which all electrons have the lowest possible energy.

A special type of notation is used to write an atom’s electron configuration. The notation describes the energy levels, orbitals, and the number of electrons in each. For example, the electron configuration of lithium is 1s 2 2s 1.
