How to write the Electron Configuration for an element 

I teach you to make the electronic configuration of atoms. that helps us to know the arrangement of electrons in an atom. For this we will use the Moeller diagram, the quantum numbers (level, sublevel, orbital and spin), the building principle and the rule of diagonals. Also to make everything faster, we will use a shortcut using kernel, where the immediate previous noble gas is used. At the end I show you a table where we see anomalous configurations that do not follow the rules or principles.
