Which of the following gases is expected to behave most ideally?

Which of the following gases is expected to behave most ideally?

Step 1: Understand what an ideal gas is. An ideal gas is a theoretical gas that follows the gas laws perfectly and has no intermolecular forces.
Step 2: Identify the characteristics of gases that behave ideally. These include small molecular size and minimal intermolecular forces.
Step 3: Look at the options given in the question. Identify which gas is a noble gas, as noble gases typically have minimal intermolecular forces.
Step 4: Among the options, select Helium (He) because it is a noble gas with very small size and weak intermolecular forces.
Step 5: Conclude that Helium (He) is expected to behave most ideally compared to other gases.
