In order to write the Sr electron configuration we first need to know the number of electrons for the Sr atom (there are 38 electrons). When we write the configuration, we'll put all 38 electrons in orbitals around the nucleus of the Strontium atom. In this video we'll use the electron configuration chart to help us write the notation for Strontium. Note that the last term in the Strontium electron configuration will be 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 Note that when writing the electron configuration for an atom like Sr, the d orbital is usually written before the s. 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 (see below for an explanation why). • Introduction to Writing Electron Configurations: https://youtu.be/J-v9_ieCqJI • Electron Configurations Chart: https://youtu.be/TjVrcw2sZLs • Writing Electron Configs Using only the Periodic Table: https://youtu.be/ououF9nHUhk • Order of d and s Orbital Filling: https://eic.rsc.org/Coature/the-trouble-with-the-aufbau-principle/2000133.article The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.Watch this short video to see if you won our element giveaway, or just to see beautiful elements!
