Question

​____ is relatively easy to ionize and thus is suitable for alternating-current applications and easier starts.

Quizplus · Accepted Answer

Argon has a lower ionization energy compared to the other options in the list, making it easier to ionize and thus suitable for AC applications and easier starts. Hydrogen has a high ionization energy and is not commonly used in AC applications. Helium and Nitrogen also have higher ionization energies compared to Argon, making them less suitable for AC applications.
