The arrangement of the electrons within a particular element can be described by an electronic configuration. This shows, with varying degrees of detail, how the electrons are arranged. Here are four different ways of writing the electronic configuration of an oxygen atom (atomic number = 8).
|Short electronic configuration||2, 6|
|Full electronic configuration||1s2 2s2 2p4|
|Full electronic configuration
