Lewis Symbols, Electron Configuration into Shells Electron Distributions Into Shells for the First Three Periods. Nevertheless, check the complete configuration and other interesting facts about Scandium that most people don't know. Electron Affinity. So, for example, neon is written using this shorthand as [He]2s 2 2p 6 rather than 1s 2 2s 2 2p 6. 5s 1 and the term symbol is 2 S 1/2 . 150 terms. A probe field at 780 nm probes and drives the D2 transition $5{S_{1/2}} \to 5{P_{3/2}}$ in all the experiments. There are 118 elements in the periodic table.
