Report Abuse. elements on the right side on the periodic table are unreactive, elements on the left are very reactive. The most unreactive elements are therefore the Noble gases.
For the first six periods of the periodic table, the noble gases are exactly the members of group 18 of the periodic table. It is possible that due to relativistic effects, the group 14 element flerovium exhibits some noble-gas-like properties, instead of the group 18 element ununoctium. Noble gases are typically highly unreactive except when under particular extreme conditions.
