A gas with: low pressure, low concentration, low temperature.
Helium is most likely to behave as an ideal gas when it is under conditions of low pressure and high temperature. Ideal gases follow the ideal gas law, which assumes the gas molecules have negligible volume and there are no intermolecular forces between them. At low pressure and high temperature, the molecules are far apart and moving quickly, closer to the assumptions of an ideal gas.
- Weak intermolecular forces -Low density
A real gas displays the most ideal behavior under conditions of low pressure and high temperature. At these conditions, the gas molecules are far apart and have high kinetic energy, resulting in weak intermolecular forces and minimal deviations from ideal gas behavior.
Real gases approach ideal behavior at high temperature and low pressure. In this Condition gases occupy a large volume and molecules are far apart so volume of gas molecules are negligible and intermolecular force of attraction(responsible for non ideal behavior) become low. So gases approach ideal behavior.

Hydrogen is close to an ideal gas under certain conditions, particularly at low pressure and high temperature. However, deviations from ideal behavior can occur at high pressure and low temperature due to intermolecular interactions and molecular size effects.

A real gas behaves most like an ideal gas when it is at low pressure and high temperature.
Oxygen gas behaves least like an ideal gas at low temperatures and high pressures. At low temperatures, the gas molecules move more slowly and can interact more with each other, deviating from ideal gas behavior. At high pressures, the gas molecules are closer together and experience stronger intermolecular forces, leading to less ideal behavior.

The ideal gas law is most applicable for a gas to exist under conditions of low pressure and high temperature.
For gases, the most ideal conditions are low pressure (p), high temperature (T), and low molar volume (V/n). This is described by the ideal gas law equation, PV = nRT, where R is the ideal gas constant. These conditions ensure that gas molecules are far apart from each other and exhibit ideal behavior.
That's called an "ideal gas". The behavior of real gases is quite similar to an ideal gas, except when the pressure is too high, or the temperature too low.That's called an "ideal gas".
