Based on Atomic Size, Which Would You Expect to Be

question 53

Multiple Choice

Based on atomic size, which would you expect to be more soluble in water: helium, He, or nitrogen, N₂?

• A)Although He is smaller, its outer orbital is filled and the atom will have little attraction to the water molecules.
• B)Since He atoms are smaller, more of them can fit into solution, so it has a higher solubility in water.
• 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.
