Sodium, Potassium, and other alkali metals are very reactive due to the low ionization enthalpy.
Flourine, Chlorine and other halogens are very reactive due to the high negative electron gain enthalpy.
Yes, fluorine is the most reactive element on the periodic table.
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.
Lithium and Fluorine.
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.
Group 1, or the alkali metals, left of the table and Group 17, the halogens, right of the table are the most reactive groups. Fr, or Francium (atomic number 87) is the most reactive metal- and fluorine the most reactive halogen. Francium and fluorine would react together explosively they are so reactive.
yes the most chemically reactive elements are in group 1
S block has the most reactive elements. The groups 1 and 2 belongs to the s block.
The most reactive elements are alkali metals and halogens.
group 17 or halogens
Cs (Caesium) is the most reactive!!!!
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..
Group 1 elements are the most reactive among metals, followed by group 2 elements.
