We’re being asked to write the electron configuration of the N3- ion.
Before we can do that, let’s first determine the electron configuration of neutral nitrogen (N) atom.
You can determine the ground-state electron configuration of Nitrogen (N) by locating the position N in the periodic table.
Ground-state means that the element is in its lowest energy form (not in an excited state). Neutral nitrogen means it has no charge, meaning no electrons are removed or added in the atom.
You can see in the above illustration of the periodic table that N is in Period 4, Group 5A, and p-block.
Write the electron configuration for N3–.
