The 35 pages that link to Noble gas, each with the reason it gives.

• OganessonBroader topic: Oganesson is placed in group 18, though its chemistry may depart from lighter members.

• Periodic lawBroader topic: Their later placement added a new group without destroying the table's recurring pattern.

• Chemical inertnessBroader topic: Their electronic structures help explain the low reactivity of many noble gases.

• Periodic table blocksBroader topic: Most noble gases end the p block; helium is the s-block exception.

• Valence shellBroader topic: Their filled valence shells help explain their characteristically low reactivity.

• Main-group elementBroader topic: The group provides a striking contrast to the reactivity of many other main-group elements.

• Period 3 elementBroader topic: Argon is the row’s terminal element, with a filled outer shell.

• Period 5 elementBroader topic: Xenon ends the row, contrasting sharply with reactive rubidium at its start.

• History of the periodic tableBroader topic: Their late discovery required adding a new group without overturning the table's periodic structure.

• Period 4 elementBroader topic: Krypton closes the period with a filled outer shell.
