The electronegativity increases
it decreases
The trend as you move from left to right across a period in the periodic table, the electronegativity increases due to the stronger attraction that the atoms obtain as the nuclear charge increases. Moving down a group, the electronegativity decreases due to the longer distance between the nucleus and the valence electron shell, thereby decreasing the attraction, making the atom have less of an attraction for electrons or protons.
Electronegativity generally decreases as you go down a group on the periodic table due to the increasing distance between the nucleus and valence electrons, reducing the attractive force. Across a period, electronegativity generally increases due to the increasing nuclear charge, pulling valence electrons closer and increasing their attraction.
Electronegativity generally increases from left to right across a period and decreases from top to bottom down a group on the periodic table. This means that elements towards the top right of the table have higher electronegativity values compared to elements towards the bottom left.
Electronegativity increases across a period , this is because the Atomic radius of elements decrease due to the nuclear charge increasing.Decending a group electronegativity decreases because atomic radius increases due to electrons moving into new main energy levels (spdf), so the most elecronegative element is fluorine Hope that helps ! xIf you didn't understand this, I am deeply sorry.
it decreases
Electronegativity decreases across a period because the effective nuclear charge increases. This causes the attraction between the electrons and the nucleus to become stronger, making it harder for atoms to attract additional electrons and thus reducing electronegativity.
The atomic number increases as one go across a period.

Across a period, electronegativity generally increases due to the increasing nuclear charge, pulling valence electrons closer and increasing their attraction.
As you move across a period in the periodic table, the atomic number increases, leading to a greater positive charge in the nucleus. This results in stronger attraction between the nucleus and the electrons, causing a decrease in atomic radius. Additionally, elements generally become less metallic and more non-metallic, with increasing electronegativity and ionization energy as you progress from left to right across the period.
Electronegativity is the ability of an atom to attract shared electrons in a chemical bond. It tends to increase as you move across a period from left to right due to increased nuclear charge. In contrast, atomic size generally decreases across a period from left to right due to increased nuclear charge pulling electrons closer to the nucleus.

It generally goes up, though there are exceptions.
Across the period (left to right), the elements tend to change from solids (metals) to gases (non metals).
