The symbol for xenon (xe) would be a part of the noble gas notation for the element

The question is incomplete. The complete question is:

The symbol for xenon (Xe) would be a part of the noble gas notation for the element antimony. cesium. radium. uranium.

cesium

Explanation:

The electron configuration of elements could be written in shorthand format. This shorthand format simply indicates the noble gas core filled by the valence electrons of the element.

Among the elements listed, only caesium has a xenon core. The electron configuration of caesium is:

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s1 which can be written in shorthand form as [Xe]6s1. Hence the answer.
