Which elements are the least reactive and which are the most reactive, and why?

The most reactive elements are the alkali metals. They react with the halogens that are also very reactive. The least reactive elements are the noble gases.

The most reactive are the halogens and the alkali metals. The least reacitve are the noble gasses. This is because they have certain numbers of valance electrons.

The most reactant are alkali metals. Halogens also mix with these metals to be reactant. The Noble gases are the least reactant.

I would have to say the most reactive elements have to be the alkali metals. With that, the least reactive elements are the noble gases. The reason why their least and most reactive, is beacause of the there number of valance elctrons.

The least reactive elements are probably the alkali metals. The Halogens are also very reactive. The least reactive metals are the noble gases.

The most reactive are the halogens. ALso the alkali metals are really reactive. THe noble gases are the least reactive.

The most reactive elements are the alkali metals. The halogens are also quite reactive elements. The least reactive elements are the noble gases.

Alkali Metals and Halogens are the most reactive. These two combine to make a super-reactive element (not really.) Noble gases are not so noble when it comes to being reactive because they are the least reactive.

The elements that react the most are the alkali metals. They are still very reactive when they react with halogens. Noble gases are the least reactive elements.

Halogens and the Alkali metals are the most reactive. The least reactive elements are the noble gases. When the both of the metals are mixed together they react with being the most reactive.

The most reactive elements are the alkali metals. Halogens are also in the most reactive group. The least reactive elements are the noble gases.
