This video on writing electron configurations for the elements accompanies the guide at https://www.Breslyn.org . You'll learn faster and remember longer is you watch the video and do the electron configuration practice problems as you watch.

One of the quickest ways to write electron configurations is to remember the trend for the orbital blocks on the Periodic Table. This way you'll be able to figure out the last term in an configuration for an element just by knowing its position on the Periodic Table.

Remember that when we write electron configurations we are generating a description of how electrons are arranged around the nucleus of an atom. Based on this information we can determine considerable information about how the atom might react to form chemical bonds, it's charge when forming ionic compounds, and other valuable information.
