How does Xenon and heavier noble gases form compounds?

2. Xenon is the heaviest nonradioactive noble gas, and so it is the easiest one to form compounds, some of which are fairly stable at room temperature and pressure. Radon would be even more easy to form compounds with, but as a highly radioactive element with no isotope having a half-life longer than 3. read more

Xenon is relatively large, and it also has some empty orbitals where it can keep more electrons. Without going into the molecular orbital theory, it’s difficult to explain everything. read more

But the heavier noble gases have more electron shells than the lighter ones. The inner electrons shield the outermost electrons, so they are less strongly attracted to the nucleus. A highly electronegative element such as fluorine can, at least, share these electrons. read more

All noble gases have full s and p outer electron shells (except helium, which has no p sublevel), and so do not form chemical compounds easily. Their high ionization energy and almost zero electron affinity explain their non-reactivity. In 1933, Linus Pauling predicted that the heavier noble gases would be able to form compounds with fluorine and oxygen. read more
