Electronegativity increases across the periodic table from left to right. It can be defined as the ability of an element to attract electrons in a bond. Let's use what we know about electronegativity to determine partial charges (distribution of electron density) within the molecule. H-F: Which element in this molecule is most electronegative? [Select] Polarity is often shown with partial charges on each atom in a bond. Which atom will have a partial negative charge? [Select] Which atom will have a partial positive charge? [Select] Which direction (along the bond) will the electron density increase (low to amazon
