Final answer:
Xenon (Xe) is the noble gas expected to show the greatest deviation from ideal gas behavior due to its larger size and stronger intermolecular forces compared to other noble gases.
Step-by-step explanation:
The noble gas expected to show the largest deviations from the ideal gas behavior is xenon (Xe). Ideal gas behavior is more closely followed by lighter noble gases like helium and neon due to their smaller atomic sizes and lower intermolecular forces. In contrast, xenon, being heavier and with larger atomic size, exhibits stronger intermolecular forces such as Van der Waals forces, resulting in greater deviation from ideal gas behavior. These intermolecular forces come into play more significantly as the size and mass of the gas particles increase, causing the gas to deviate from the ideal assumptions of no intermolecular interaction and particles occupying negligible space.
