Here's how to draw the Lewis diagram for atomic nitrogen:

1. Symbol: Start with the symbol for nitrogen, which is "N".

2. Valence Electrons: Nitrogen has 5 valence electrons. Place these electrons as dots around the symbol, one at a time, following the rules:

* Place one dot on each side of the symbol (top, bottom, left, right)

* Pair up remaining electrons (if necessary) on the same sides, starting from the top.

Here's the final Lewis diagram:
