Electronegativity Explained
Electronegativity decreases as you move down the periodic table due to increased electron shielding from inner shells, despite having more protons. Conversely, moving to the right increases electronegativity because of the greater pull from additional protons. Additionally, paired electrons are more stable than unpaired ones, leading unpaired electrons to seek pairing with others for stability.In this clip
