Aufbau Principle Diagram Example. For example carbon has 6 electrons and its electronic configuration is 1s 2 2s 2 2p 2. 1s 2 2s 2 p 4.
The following steps detail how to draw an aufbau diagram. 1s 2 2s 2 p 4. When there are two electrons in an orbital the electrons are called an electron pair.
It is important to note that each orbital can hold a maximum of two electrons as per the pauli exclusion principle.
Fill the s orbital in the first energy level the 1s orbital with the first two electrons. This would be written as. An arrow pointing up denotes an electron spinning one way and an arrow pointing downwards denotes an electron spinning the other way. Principal energy levels are color coded while sublevels are grouped together and each circle represents an orbital capable of holding two electrons.
