The electron configuration of an element shows how electrons are distributed in orbitals— which ones are filled and which ones remain vacant. We can predict the electron configuration of

Objectives. To determine the electron configuration of any of the first 38 elements of the periodic table. To determine the identity of an element from its electron configuration. To complete an orbital diagram using arrows to represent electrons.
Chemistry 101 . Chapter 8 . ELECTRON CONFIGURATION AND THE PERIODIC TABLE. The electrons in an atom fill from the lowest to the highest orbitals. The knowledge of the location of the orbitals on the periodic table can greatly help the writing of electron configurations for large atoms. 15.

This list of electron configurations of elements shows all the elements by increasing atomic number. Print the PDF as a useful study sheet.
By “building up” from hydrogen, this table can be used to determine the electron configuration for any atom on the periodic table. We will now construct the ground-state electron configuration and orbital diagram for a selection of atoms in the first and second periods of the periodic table.
‣ Changing the configuration of electrons in an atom, changes it’s chemical properties. Like a computer program. ‣ Many important chemical reactions are initiated by exciting electrons from one configuration to another. ‣ We call the lowest energy electron configuration of an atom it’s ground state. It’s the rest state of the atom.
