Electrical stability of an atom

  1. Oct 18, 2011 #1
    1. The problem statement, all variables and given/known data
    As shown in class the electric potential energy of a water molecule is -5.33 eV. Which molecule is more electrically stable, H2O or CO? Why?


    2. Relevant equations
    EPE=Kc*q1*q2/r12


    3. The attempt at a solution

    The water molecule's EPE is -5.33 eV. The carbon monoxide molecule's EPE is -2.04 eV. Am I correct in believing that the carbon monoxide molecule is more stable, as the magnitude of its charge is lower?

    The question has do do with potential energy, not charge.

    Alright then, let's see . . .

    eV is a unit of energy. Therefore would I be correct in concluding that the CO molecule has a quantity of energy closer to zero and therefore it would be more electrically stable?
