Among the elements listed (O, K, Mg, Xe), xenon (Xe) is the least reactive. Xenon is a noble gas, which means it has a full valence shell and is generally inert, making it much less reactive than the other elements in the list. Oxygen (O), potassium (K), and magnesium (Mg) are all more reactive than xenon.
