Question

Which statement is true about the atoms in helium gas?

A. They have strong attractions to one another.
B. They are not closely packed.
C. They are arranged in an orderly pattern.
D. They travel in circular paths.

Answer 1

The appropriate answer is a. they are not closely packed. Molecules in a gas are not closely packed but a scattered in a rather disorderly fashion. Atoms packed or arranged in an orderly pattern are solids. Helium atoms would not have an attraction to each other because helium is an inert gas. Inert gases are nonreactive.
