In a fifth experiment, Experiment E, marble 1 has a pre-collision momentum of 20 units. The total post-collision momentum of marbles 1 and 2 is measured as 40 units. Which of these momenta is most likely the pre-collision momentum of marble 2?

Ithink is a because if say increased in electronegativity

Ions gain or lose electrons
