Which family of elements is the least reactive?

No! The noble gases are the least reactive elements.

The noble gases are the least reactive among all chemical elements.

Halogen group of elements is highly reactive.

Generally, the least reactive elements are the noble gases.

No, they are the least reactive elements. That is why they are called the noble gasses.

Noble gases are the least reactive elements because they have a full valence shell.

The least reactive element in the group 2 of the periodic table of elements is beryllium.

The most reactive halogen, and one of the most reactive of all the elements, is fluorine. Reactivity in the halogen family continues in order from most reactive to least reactive with chlorine, bromine, iodine, and astatine.

The Zinc Family also known as group IIB is the second least reactive I believe. The least reactive family is the one with a full p sublevel, the noble gases, the next least reactive would be the family with a full d sublevel. Since group IIB has a full d sublevel, it must be the next least reactive family.

fluorine is the most reactive halogen, astatine is the least reactive.

It is one of the least reactive elements.

Group 1 elements - lithium, sodium, potassium, rubidium and caesium - are reactive with water.

Yes noble gases are least reactive. They are stable in nature.

The most reactive nonmetal is fluorine

Noble elements are least reactive. They belong to group-18.

its the noble gases that are the least reactive group among the elements; and they occupy the left most group i.e. 18th group in the periodic table.

Group 8 or Noble gasses have the least reactive elements in the periodic table

they are the least reactive elements

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.

From these elements, potassium is most reactive, calcium comes second and copper is the least reactive.

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.

Ra, Ba, Sr, Ca, Mg , Be

Yes. Noble gases are least reactive among all the elements as they have completely filled orbitals.

He, Ne,Ar, Kr,Xe, Rn are the inert elements in the Table , so they are least reactive.

Sodium or Na is in the Alkali Metals family or Group 1. All the elements in that family but Hydrogen or H are very reactive. It's very simple to find out which is the most reactive. The farther down the list of go in the Alkali Metals the more reactive the element is. So Lithium or Li is the least reactive of them all and Francium is the most reactive of them all.
