The two most reactive groups of elements in the periodic table are the alkali metals and the what?

The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.


Are the elements on group 17 on the periodic table reactive?

Yes


Which group are highly reactive non metals on the periodic table?

The halogens are the highly reactive nonmetals on the periodic table. This group includes elements such as fluorine, chlorine, bromine, and iodine, which readily form compounds with other elements due to their strong tendency to gain an electron.


Which of the following is an extreamly reactive family of elements?

The halogens are an extremely reactive family of elements in the periodic table. They have a tendency to gain an electron to achieve a full outer shell, making them highly reactive with other elements.


What are the highest and lowest reactive elements on the periodic table?

As you move left on the periodic table, the elements get more reactive and as you move down the periodic table. Using that thinking the most reactive elements are the Alkali Earth Metals (column 1) and the most reactive element is Francium. The least reactive are the noble gases in the last column- Helium, Neon, Argon etc..


What are 2 elements most reactive on periodic table?

Lithium and Fluorine.


What elements are reactive?

There are many reactive elements. They show up more on the upper left of the Periodic Table. Some of these are plutonium, uranium, Mercury and lead.
