Helium will show the same behavior like an ideal gas. Helium, however, is a very small particle, is extremely non-polarizable, and has very low inter-atomic forces( little force of attraction). This results in a very low boiling point, about 4 Kelvins. Thus, helium will demonstrate ideal gas law behavior to temperatures much closer to its boiling point and to much higher pressures when compared to other gases.
