8) rubidium [kr]5s has an atomic radius of 248pm. tin, another period 5 element, has an
atomic radius of 140pm.
what would the correct atomic radius for xenon be? xenon is also in period 5 and a noble gas.

140 pm.

Explanation:

Xenon is an element under the Noble gases group and on period 7 of the periodic table. This element is most notable for its bright luminescent in light bulbs. Xenon is unique for being the first noble gas element to be synthesized into a compound. Xenon differs from the other noble gases by being heavier and denser than most.
