Electron Configuration Of Sodium Chloride. A common example of a compound containing a chloride ion is table salt or sodium chloride. It is in group 7 of the periodic table.
In writing the electron configuration for sodium the first two electrons will go in the 1s orbital. Therefore, it has 18 electrons and seventeen protons. Potassium electron configuration notation the configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.
The atoms before and after helium (h and li) follow a duet rule and tend to have the same 1s2 configuration as helium.
Electron configuration of elements tested element electron configuration k 1s2 2s2 2p6 3s2 3p6 4s1 li 1s2 2s1 na 1s2 2s2 2p6 3s1 ca 1s2 2s2 2p6 3s2 3p6 4s2 table 4: In writing the electron configuration for sodium the first two electrons will go in the 1s orbital. The electronic configuration for sodium, using noble gas (abbreviated) notation is, [ne] 3s1. Since 1s can only hold two electrons the next 2 electrons for sodium go in the 2s orbital.
