Out of the gases He, Ne, Kr, and Xe, which one is least likely to obey the ideal gas laws at very high pressures and very low temperatures and why?

At low temperatures or high pressures, real gases deviate significantly from ideal gas behavior. It is also good to know that ideal gas law assumes that the gas molecules have negligible/no size.
Keeping that in mind, Xe is the largest of the bunch, and therefore is expected to have the greatest deviation of the ideal gas when under high pressure or low temperature.

Hope this helped (c:
