xenon is reactive but it is a very little reaction that will happen.
Xenon is a noble gas. It is chemically inert (or non-reactive).
It is not. Xenon barely reacts at all.
No.
Nickel is more reactive.
Non-reactive.
XENON
No, it is not.
Bromine is way more reactive
No, it is a noble gas.
Calcium.
In order from least reactive to most, the order is xenon, nickel, then lithium. I determined this based in the theory that non-metals are less reactive.
