Webb23 apr. 2024 · Atomic Number. As the atomic number of an element increases, so does the size of its nucleus and the number of electrons around it. The bigger the atomic number, the larger the atom’s radius. This is especially true as you move straight down a given column on the periodic table; the radius of each successive neighboring atom increases.

From there on, we see our general trend again. The ionization energy for fluorine is up to 1681, and then again for neon, we see an increase in the ionization energy due to the increased effective nuclear charge.
