Atomic Radii increases down the periodic table and to the left
So not looking at the ions largest to smallest goes
Li, Mg, N, F
Now just the ions
All the ions are the same because F- has 9 electrons + 1 = 10 electrons so Neon
Na + is 11 electrons - 1 = 10 electrons so Neon
Al 3+ is 13 electrons -3 = 10 electrons so Neon
Now with the Atoms and Ions together it would be
Largest-----Smallest
Li, Mg, N, Ne, F
F atom is the smallest
