The two groups of elements in the periodic table that are the most reactive are alkaline earth metals and halogens.
The two groups of elements in the periodic table that are the most reactive are the alkaline earth metals and halogens.
The two groups of elements in the periodic table that are the most reactive are the alkaline earth metals and the halogens.
To determine this, you can refer to the periodic table itself, which organizes elements based on their properties. The alkaline earth metals can be found in Group 2, located on the left side of the periodic table. These metals are highly reactive because they have two valence electrons that they readily lose to form positive ions.
On the other hand, the halogens are found in Group 17, on the right side of the periodic table. These elements are also highly reactive because they have seven valence electrons, and they readily gain one electron to complete their valence shell and form negative ions.
Therefore, the alkaline earth metals and the halogens are the two groups in the periodic table that exhibit the most reactivity.
