Electronegativity decrease going down in a group and increase from left to right; but this isn't a general rule.
A similar situation is also with the ionization energy.
Plutonium is neither an ionization energy nor an electronegativity. Ionization energy is the energy required to remove an electron from an atom, while electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond. Plutonium is a heavy radioactive element with a variety of chemical properties.
Metallic character and ionization energy are inversely related. Metallic character increases as one moves down a group in the periodic table, while ionization energy decreases. This is because metals tend to lose electrons easily, indicating lower ionization energy, whereas nonmetals, which have higher ionization energies, are less metallic in character. Thus, elements with high metallic character typically have lower ionization energies.
As you go down a group in the periodic table, metallic characteristics increase. This is because atomic size increases, leading to a decrease in ionization energy and electronegativity. These trends make elements more likely to lose electrons and exhibit metallic properties such as malleability, ductility, and good electrical conductivity.
This is the second ionization energy.
Ionization energy and electronegativity are both periodic trends that help explain the behavior of elements in the periodic table. Generally, ionization energy increases across a period from left to right and decreases down a group, while electronegativity also increases across a period and decreases down a group. This relationship arises because elements with higher ionization energy tend to attract electrons more strongly, leading to higher electronegativity. Both properties reflect the effective nuclear charge experienced by valence electrons, influencing an element's reactivity and bonding characteristics.
When electronegativity decrease the first ionization energy also decrease.
Electronegativity and first ionization energy both increase going up the Periodic Table.

Ionization energy would be similar.
First ionization energy has a trend similar to that of electronegativity.

Electronegativity and first ionization energy both increase as you move up the periodic table
Electronegativity and first ionization energy both increase going up the Periodic Table.
The electronegativity trend and the first ionization energy trend both increase as you move from left to right across a period in the periodic table due to the increasing effective nuclear charge. Higher electronegativity indicates a stronger pull on electrons, making it harder to remove an electron, thus increasing the first ionization energy.
As we move from left to right across Period 3 from Na to Cl, electronegativity and first ionization energy generally increase. This is due to the increasing effective nuclear charge as electrons are added, causing a stronger attraction between the nucleus and outer electrons. Chlorine, being closer to the right of the period, has a higher electronegativity and first ionization energy compared to sodium.
