The two most reactive groups of elements in the Periodic Table are the alkali metals and halogens.
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
The two columns of elements in the periodic table that contain the most reactive elements are columns 1 and 17, the alkali metals and halogens respectively.
the alkali and alkali earth metals (groups 1 and 2) are the most reactive.
The alkali metals and the halogens are the most reactive groups and among them, francium and fluorine are the most reactive, especially with each other.
Generally the most reactive elements in the periodic table are found in the first two (left-most) columns: the alkali metal and alkali earths.
The alkali metals are more reactive because they react readily with the atmospheric oxygen forming their respective oxides and hydroxides.
The most reactive elements are found in groups 1 (alkali metals) and 17 (halogens) which contain the elements with one valence electron and seven valence electrons respectively.
Alkali metals is the most reactive group.They are very reactive metals.They do not occur freely in nature.
Groups I and VII.
Group 1 the Alkali Metals and Group 2 the Alkaline Metals. Group 1 is more reactive than Group 2.The three major reactive groups of elements are the alkali metals, Alkaline Earth and halogens (these groups are labeled 1 or IA, 2 or IIA, and 17 or VIIIB respectively)
The first cloumn in the periodic table has the most reactive elements. The elements decrease in reactivity as you go across the table. in other words alkali metals
the alkali metals are the most reactive... either cesium or francium would be the most reactive out of this group.
The most reactive metals are in the group 1 of the periodic table - the alkali metals.
The alkali metals are the most reactive of all groups on the periodic table. Some of the metals are lithium, potassium and sodium.
The most reactive group in the periodic table is none other than Group 1. Group 1 refers to alkali metals.
The most reactive elements on the periodic table are the alkali metals. Starting just under Hydrogen on the far left of the table is the first alkali metal atomic #3 Lithium, #11 Sodium (the fun metal :o), and so forth and so on down the column to atomic #87 Francium. science teacher
Alkali metals are elements located in the group 1 of the periodic table. Transitional elements are located in the d and f groups of the periodic table. Hence, they are completely different.
Well, No options were given in the question. But normally group 1 (alkali metals) and group 17 (halogens) are the most reactive groups.
S block has the most reactive elements. The groups 1 and 2 belongs to the s block.
Group 1 elements are the most reactive among metals, followed by group 2 elements.
The halogens or halogen elements which are a series of nonmetal elements from Group 17 of the periodic table, the most reactive being fluorine (F).
Group 1A are Alkali metals and 7A are Halogens. Both groups comprise very reactive elements.
