This element is most likely to be found in Group 18, the noble gases, on the periodic table.

Here's why:

* Low Boiling Point: Noble gases exist as single atoms, with very weak interatomic forces (van der Waals forces). These weak forces result in low boiling points, as very little energy is required to overcome them and cause the atoms to separate into a gaseous state.

* Low Reactivity: Noble gases have a full outer shell of electrons, making them very stable and unreactive. They rarely form chemical bonds with other elements.

Examples: Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn) are all noble gases with extremely low boiling points and very low reactivity.
