By looking at the electron configuration of selenium, it is possible to determine how many electrons are in each sub-shell. This configuration conveys a lot of important information about an element. The term electronic configuration refers to the arrangement of the electrons around the central nucleus from the inner energy shell to the outer energy shell. 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). An energy level diagram is more useful and easier to work with than quantum numbers in the quantum mechanical model. 3d 5 4s 1 and 3d 10 4s 1 respectively which are more stable than partially filled orbitals such as 3d 4 4s 2 or 3d 9 4s 2.. We must first check the atomic number of V, which is 23. The element Y is coming just below the element in same group. What is x? The name for electron shells came from the Bohr model , which states that electrons orbit the nucleus at certain distances so that their orbit formed "shells". Chapter 7 Electronic Configurations and the Properties of Atoms - 3 - In this text, we will arbitrarily assign ms = +½ to electrons represented with an upward arrow (also called “spin up” electrons) and ms = ½ to electrons represented with a downward arrow (also called “spin down” electrons). These noble gases have completely filled outermost shells and can be prefixed to the outermost shell of the element whose electronic configuration must be noted. There are five sub-shells, but only four of them are used by naturally occurring elements: s, p, d and f. Since it can have either one or two electrons, its called as $1s^1$ and $1s^2$ respectively.
