Consider the elements in the periodic table. as we move to the far right, the purple column is made up of that are a) gases; nonreactive b) metals; nonreactive c) metalloids; reactive d) gases; highly reactive

Towards the extreme right of the periodic table is the group 18 which corresponds to the noble gases. Helium, Neon, argon, krypton and xenon. These gases have a completely filled outer or valence shell and have a general electronic configuration represented as: ns²np⁶. This fully filled configuration makes these gases extremely stable and inert.

As we move to the far right, the purple column is made up of gases that are nonreactive.

Ans: A)
