Determining Ionization Energy of Metals

[Christian Velazquez 2B]

How do we find the ionization energy of metals, does this relate to the periodic table, is a higher energy correlate to a stronger bond and vice versa. And what does it mean

all i know is that ionization follows the same trend as electronegativity, so it means that metals have low ionization because they are to the left of the periodic table.

Ionization energy increases as you move left to right across a period and up the groups. Atomic radius follows the opposite trend. With that in mind, ionization energy increases as the atomic radius of the atom gets smaller, because the outermost electrons are closer to the nucleus and held more tightly together, requiring more energy to remove. Ionization energy decreases as the atomic radius gets bigger because the valence electrons are farther from the nucleus, meaning it is held less tightly and requires less energy to remove. Metals have low ionization energy, so they tend to lose electrons during chemical reactions (get oxidized) and form cations.
