Under what conditions will a gas be least likely to exhibit the ideal gas properties predicted by the ideal gas law?

That the particles of the gas do not have inter-molecular interactions The particles are in random Brownian motionThe gas occupy an infinite volume The collision between particles and between the particles and the walls of the container The temperature of the gas is directly proportional to the average kinetic energy of the particles of the gas

Cr(oh)3 -> cr(3+) + 3oh-

They are all full and don't need any more electrons in there outer shell.
