• Step 2: Go back to the last noble gas that was passed (atomic number).
• Step 3: Write the symbol of the noble gas in brackets to start your electron configuration.

Answer 2

Answer:

A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration.
