The noble gas configuration means that the electronic configuration for Lithium is written in shortcut by starting with the symbol for the nearest noble gas. Note that the noble gas should be lighter than the said element. In here, the nearest noble gas to Lithium is Helium (He). Then, add the additional electrons. Thus, the noble gas configuration would be: <em>[He]2s¹.</em>
