Writing Electron Configurations Using Only the Periodic Table
Writing Electron Configurations Using Only the Periodic Table
A step-by-step description of how to write the electron configuration for elements using just the Periodic Table.
In order to write the electron configurations using the Periodic Table we first need to know the number of electrons for the each atom. When we write the configuration we'll put these electrons in orbitals around the nucleus of the atom.
Electron 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.
You can also use just the Periodic Table to help write the notation elements instead of the Periodic Table. See https://youtu.be/ououF9nHUhk.
