how does electronegativity relate to the periodic trends of atomic properties? How does effective nuclear charge, the concept invoked to understand those trends, also help explain the trends in electronegativity?
The tendency to attracted the bond pair of electrons attracted towards its self is called electronegativity.
In a group top to bottom atomic radius increases nuclear attraction decreases over the valency electrons. So electronegativity decreases in a group top to bottom.
in the long form of periodic table more lectronegative elements are halogens.
In a period left to right atomic radius decreases nuclear attraction increases over the valency electrons. So electronegativity increases in a period left to right.
In a group electronegativity decreases elcropositivity increases and metallic charecter increases.
In a period electronegativity increases elcropositivity decreases and metallic charecter decreases.
