• "The disparity in electronegativity values between the oxygen and the phosphorus (3.5 for O compared to 2.1 for P), along with the formal charges on 3 of the 4 oxygens, compounded with the oxygen atoms having electron lone pairs makes this molecule pretty reactive."
• "HMAs are formed from alloys that are highly mismatched in terms of electronegativity, which is a measurement of their ability to attract electrons."
• "Going along a row from left to right, the reactivity increases, and properties such as electronegativity increase as well."
