The least reactive elements are the noble gases (helium, neon, krypton, argon, xenon). They each have a complete outer electron shell (two electrons for helium, eight electrons in the outer shell of the other noble gases). Chemical reactions take place in ways that result in making outer electron shells more complete (or for transition state elements, it can also make inner shells more complete), so if the outer electron shell is already complete, there is no basis for a chemical reaction.

rubidium
The least active elements are the .?
Generally, the least reactive elements are the noble gases.
What is the least reactive groups on the periodic table?
Noble gases are least reactive because they have a full shell
Which group has the least reactive elements?
Nobel gases.
What elements has the least reactive metal?
magnesium (Mg)
What is the reactivity of xenon?
It is one of the least reactive elements.
What family is non reactive?
The noble gases are the least reactive among all chemical elements.
What common characteristic is generally shared by the elements at the center of a period?
they are the least reactive elements
Which element is the least reactive in period 4?
Noble gasses are least reactive of all the elements. So the least reactive element in the period 4 is Krypton. It is a noble gas with an atomic number of 36.
What is the most non-reactive family?
The noble gases are the least reactive among all chemical elements.
Why were least reactive elements discovered before more reactive elements?
The simple reason is that least reactive elements are mostly found in their native state while reactive elements are found in combined state (in form of their compounds). It is easier to extract any element in it's native or elementary form. Such elements can be easily separated from their ore. They are separated by using physical processes. Reactive elements need to be extracted from their minerals through chemical processes which are more expensive and tedious.
