13267317935 | Periodic Trend: Electronegativity | Across the period: increases the effective nuclear charge increases - they have a stronger pull on their electrons and are more likely to attract new ones. they have more electrons in their valence shell it is easier to fill the shell by gaining rather than losing electrons Down the group: decreases as the principal energy level increases, they do not have as strong of a hold on their electrons and are less likely to attract more (the shell becomes bigger and the valence electrons are farther away from the nucleus).
