Electron configurations Bed Check for Electrons

Chemists find quantum numbers useful when they re looking at chemical reactions and bonding (and those are things many chemists like to study). But they find two other representations for electrons more useful and easier to work with  

Chemists use both of these things to represent which energy level, subshell, and orbital are occupied by electrons in any particular atom. Chemists use this information to predict what type of bonding will occur with a particular element and show exactly which electrons are being used. 

These representations are also use l in showing why certain elements behave in similar ways. 

In this section, I show you how to use an energy level diagram and write electron configurations. 

In using the energy level diagram, remember two things
