An element's location on the table can be used to determine its electron configuration. By following the order of periods (rows) and blocks (s, p, d, f), you can trace how electrons fill the atom's orbitals and efficiently determine the distribution of electrons in an atom. • Sections: • 00:00 - Introduction • 00:45 - Periodic table layout - periods and groups • 02:10 - Period and valence shell number • 02:52 - s, p, d, and f block elements • 04:25 - Finding the number of valence electrons • 05:38 - Modified periodic table for writing electron configurations • 06:14 - Electron configuration of hydrogen, helium, lithium • 07:47 - Electron configuration of carbon chlorine • 09:33 - Electron configuration of d-block elements • 12:58 - Noble gas shorthand • Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
