For example, if you need to write electron configuration of Erbium (68), cross out elements 69 through 120. However, the “shorthand” electron configuration offers a shortcut that saves a lot of time and makes the configuration easier to read. Commonly, the electron configuration is used to describe the orbitals of an atom in its ground state, but it can also be used to represent an atom that has ionized into a cation or anion by compensating And, we can now see an ever shorter way to represent the electronic structure of an atom, we can just write down how many electrons are present in each shell (energy level) separated by a comma, and this shorthand is referred to as the electron configuration or electronic configuration of the atom. Xenon. Therefore, we should not be surprised that when many monatomic ions form, they gain or lose electrons to achieve a 1s 2 or ns 2 np 6 configuration.
