Unformatted text preview: oxidizing agents) are electronegative substances (upper right-hand corner of periodic table. They pull electrons from other substances to form an octet.) Most easily oxidized (highest potential to be oxidized; best reducing agents) are electropositive substances (lower left-hand corner of periodic table. They donate electrons to other substances to form an octet.) o Spontaneous reactions E cell must be positive. (G sys must be negative; S univ must be negative)...
