Answer: No, it would not gain or lose electrons easily.
Step-by-step explanation:
Since radon is a noble gas, and noble gases are relatively stable due to their full outer shell, with 8 valence electrons. This form is the most stable one, so they do not need to gain or lose to become more stable.
Because it is a noble gas, it has quite a large ionisation energy as well. I do not expect many ions forming from Radon.
