What best describes the motion of helium atoms in gaseous helium?
The helium atoms move quickly in all directions. This is cap
What is true about atoms in helium gas?
They are helium atoms and have all the properties of helium. Helium is mono-atomic [as are all of the noble gases] Non-noble gases [those gases that react with other elements/compounds] are diatomic meaning that in the gaseous state the atoms are paired on to another.
Is helium a gaseous mixture at room temperature?
Helium is gaseous but it is not a mixture - it is a chemical element.
Is liquid helium boiling a physical property?
Yes. conversion of liquid helium to gaseous helium is a physical property
