Unformatted text preview: quot;hold" UP TO two electrons.
Here is the list of ALLOWED orbitals in order of INCREASING ENERGY (Aufbau order)
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 8s
NOTICE some (e.g. 2f, 1p, etc.) do NOT exist!
THE AUFBAU ORDER
One way to remember this is to write the orbitals out as shown:
THEN add the lines: READ OFF in the order you get to them as you
follow the arrows and work downwards.
NOW we have the names and ORDER of the orbitals we put the
electrons in them! ELECTRON CONFIGURATION (Putting the electrons away in orbitals)
We use sup...
