Based on atomic size, which would you expect to be more soluble in water: helium, He, or nitrogen, N2?
A. Since He atoms are smaller, more of them can fit into solution, so it has a higher solubility in water.
B. Although He is smaller, its outer orbital is filled and the atom will have little attraction to the water molecules.
C. Nitrogen atoms are bigger and so nitrogen molecules should be more soluble in water due to greater dipole-induced dipole attractions.
D. He atoms are bigger and so helium molecules should be more soluble in water due to greater dipole-induced dipole attractions.
